What happens if I use the wrong resistor?

If you are using such a resistor in a current-sensing application in a switch-mode circuit, you will get spurious readings or inaccurate behaviour. For a simple LED circuit there are no bad consequences of using a resistor of higher power.

What happens if I use a higher ohm resistor?

When we replace a resistor with a higher value of resistor, the current in the circuit will decrease by an amount depending upon the value of the new resistor. Where E = voltage in the battery/cell and r = internal resistance of the circuit.

What happens if you don’t use a resistor with an LED?

When hooking up an LED, you are always supposed to use a current-limiting resistor to protect the LED from the full voltage. If you hook the LED up directly to the 5 volts without a resistor, the LED will be over-driven, it will be very bright for a while, and then it will burn out.

Does it matter what type of resistor I use?

Summary. For most standard circuits, you don’t need to worry about the types of resistors you choose. All you need to worry about is the resistance value and how much power it can take.

Why do you need 330 ohm resistor for the LED?

330 ohms may be used by some people as a “get you going” value that works “well enough” in many cases. The purpose of the resistor is to “drop” voltage that is not required to operate the LED, when the LED is operating at the desired current.

Do I need a resistor for LED?

An LED (Light Emitting Diode) emits light when an electric current passes through it. The simplest circuit to power an LED is a voltage source with a resistor and an LED in series. Such a resistor is often called a ballast resistor. If the voltage source is equal to the voltage drop of the LED, no resistor is required.

What color is a 330 ohm resistor?

Thus, for 330-ohm resistor, 1st digit is ‘ 3 ‘, ∴ look for color in a chart with value 3, then it’s your 1st color(say orange). The next 2nd digit is ‘ 3 ‘, ∴ look for color in a chart with value 3, then it’s your 2nd color (say orange).

How do you calculate the tolerance of a resistor?

Tolerance = value of resistor x value of tolerance band = 220 Ω x 10% = 22 Ω 220 Ω stated resistance +/- 22 Ω tolerance means that the resistor could range in actual value from as much as 242 Ω to as little as 198 Ω.

What is the tolerance of a resistor?

The tolerance of a resistor is the maximum difference between its actual value and the required value and is generally expressed as a plus or minus percentage value. For example, a 1kΩ ±20% tolerance resistor may have a maximum and minimum resistive value of: Maximum Resistance Value.

What is tolerance formula?

Then, the interval [L, U] is a two-sided tolerance interval with content = P x 100% and confidence level = 100(1 – α)%. Such an interval can be called a two-sided (1 – α, P) tolerance interval. For example, if α = 0.10 and P = 0.85, then the resulting interval is called a two-sided (90% , 0.85) tolerance interval.

How do you find the minimum and maximum value of a resistor?

First find the “nominal resistance,” or 470K in this case. Take the nominal value and multiply it by 1 + your tolerance, which is (1+0.1). Then take the nominal value and multiply it by 1 – tolerance, or (1-0.1). The highest possible value is 517 K.

What is maximum resistance?

It is know to us , combining resistances in parallel reduces equivalent resistance and combining resistances in series increases equivalent resistance. To get maximum possible resistance, one has to combine all 5 resistors in series. Rmax​=R1​+R2​+R3​+R4​+R5​ Rmax​=R+R+R+R+R=5R. Rmax​=5×51​=1Ω

How can one correctly read the color codes and tolerance value of a resistor?

Always read resistors from left to right. – Resistors never start with a metallic band on the left. If you have a resistor with a gold or silver band on one end, you have a 5% or 10% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.

How do you determine the value of 5 band resistors?

Let’s take an example of a 5-band resistor with the colors given in the above image (brown, green, red, black and gold). So according to the formula the resistance will be: 152 * 1 = 152 Ohms with 5% tolerance.

What is the value of a resistor which has first three color bands are red black and orange?

The third band is the multiplier band and color-codes are as Black is 1, Brown is 10, Red is 100, Orange is 1000 (1 K), Yellow is 10,000 (10 K), Green is 100,000 (100 K) and Blue is 1,000,000 (1 M).

How do I know what resistor to use with LED?

We’ll use the following formula to determine the resistor value: Resistor = (Battery Voltage – LED voltage) / desired LED current. For a typical white LED that requires 10mA, powered by 12V the values are: (12-3.4)/. 010=860 ohms. To use several LEDs in parallel, sum the current values.

Which is the best resistor?

Metal Oxide Film They are similar to metal film with the difference that the resistive material is a metal oxide, such as tin oxide. These durable resistors feature a better reliability and stability than metal film resistors.

What kind of resistor do I need for LED?

The resistor must have a value of at least 183.3 ohms. Note that the voltage drop is 5.5 volts. It would have been possible to connect additional LEDs in the circuit.

Do you put the resistor before or after the LED?

It doesn’t matter! The resistor can go before – or after – the LED, and it will still protect it. the current that flows out of a battery is always equal to the current that flows back into the battery.

Do you need load resistor for LED lights?

Theory (1) LED turn signal installation of the front or rear only while using bulb lights at the opposite end (front or rear) does not require flash controllers/resistors. Theory (3) A flash controller/resistor is necessary for every LED turn signal or light that is installed.

Is Hyper Flash illegal?

Hyper flashing is commonly associated with the problems of having LED lights for your blinkers. Typically, hyper flashing is regarded as when your blinkers are flashing around 105-115 times per minute. This will cause a variety of issues for other drivers on the road and may even be illegal.

Do LED load resistors get hot?

These resistors get very hot when under constant load but for a turn signal, it won’t get as hot – still, securing to a metal surface is critical.

Why do LED hyper flash?

The lower resistance level is detected by the vehicle as a burned-out bulb, which would cause the LED light to hyper-flash. In order to avoid hyper-flashing, LED upgrades are designed with a resistor that simulates a standard bulb and provides your vehicle with the resistance it needs to work properly.

Do LED turn signals need a load equalizer?

LED bulbs are more efficient than incandescent bulbs and consume less power. A Load Equalizer is required for each incandescent turn signal lamp that is replaced by an LED experiencing ‘bulb-out’ or ‘hyper-flash’ warnings.

What is a LED load equalizer?

A Load Equalizer is used as a power-sink, to dissipate the same amount of power as the OEM turn signal lamps did.

What is a LED flasher relay?

The LED flasher unit is a solid state electronic device that is specifically designed for use on vehicles fitted with LED lights. Additionally, the flasher relay has the unique ability to control the flash rate of the vehicles LED directional indicators.

Is a load equalizer the same as a resistor?

Load equalizers and resistors are pretty much the same thing. You can just use resistors and wire them across the load (parallel) to simulate the OEM lamp. Usually, an 8-10 Ohm resistor will do the trick, but I’d recommend at least a 20 Watt resistor to avoid overheating.

How many load equalizers do I need?

Headwinds: Load Equalizers are required for turn signals only. flasher thinks that one bulb is burnt out. A load equalizer should be connected to which ever set of turn signals they replace. rear turn signals you need two load equalizers, one for the front and one for the rear.

Do I need an LED flasher relay?

if you replace any pair of turn signals with leds, you’ll need a relay or resisters. the relay is plug/play and works VERY well.

Do I need a special flasher for LED lights?

The reason most mechanical flashers won’t work with LEDs is that they require very little current flow, which is not enough to heat the internal strip and open the circuit. There are several types of electronic flashers available, however, not all of them are for LED applications.

Will a regular flasher work with LED lights?

LEDs are used for flashing beacon lights on vehicles such as maintenance trucks. The reason most mechanical flashers can’t work with LEDs is that LEDs need a small amount of current flow, not enough to heat the internal strip and open the circuit.

What kind of flasher do I need for LED lights?

JEGS LED Turn Signal Flashers are required for use with LED tail lights & turn signals. LED turn signals use much less power than standard incandescent bulbs and won’t work correctly with a standard flasher. Choose from 2-terminal or 3-terminal style flashers to match your existing vehicle wiring.

What is LED flasher circuit?

An LED flasher circuit is a circuit which flashes the LED- meaning turns it ON-OFF, ON-OFF, ON-OFF. The 555 timer chip is a very versatile IC, because when connected correctly, it can it can create pulses of current at specific time intervals decided by the resistor-capacitor (RC) network.
