What is voltage and what is its relationship to amperage and power 4 points?
The voltage is the source, the amperage is the current, and the resistance is the measure of how much that component slows the flow of electrons. Investigate the difference between series, parallel and series/parallel circuits. Series: In a series circuit, electrons can travel along only one path.
What are the relationship between voltage and current?
Ohm’s law defines the relationship between the voltage, current, and resistance in an electric circuit: i = v/r. The current is directly proportional to the voltage and inversely proportional to the resistance.
What kills a person voltage or current?
Current will kill you but some amount of voltage is required to flow that current in the body breaking the human body resistance. In other words, an enough power is required to pass in the human body for proper electric shock.
Why does voltage cause current?
Voltage generates the flow of electrons (electric current) through a circuit. The specific name for the source of energy that creates the voltage to make current flow is electromotive force. Electrical energy is the energy released when a charge ‘falls’ through a potential difference (voltage).
Does current follow voltage?
Voltage causes current through a closed circuit, but through an inductor it is the change in current that causes a voltage. Obviously there is no current without voltage. In a simple DC circuit there’s no doubt that voltage causes the current to flow.
Does voltage depend on current?
The force motivating charge carriers to “flow” in a circuit is called voltage. Voltage is a specific measure of potential energy that is always relative between two points. The amount of current in a circuit depends on the amount of voltage and the amount of resistance in the circuit to oppose current flow.
How does voltage drive current?
When a voltage source is connected to a circuit, the voltage will cause a uniform flow of charge carriers through that circuit called a current. In a single (one loop) circuit, the amount of current at any point is the same as the amount of current at any other point.
What is the difference between power voltage and current?
Voltage, also called electromotive force is simply the energy per unit charge. In other words, voltage is the difference in electric potential between two points….Related Articles:

What exactly is voltage and current?
A voltage appears whenever there is an imbalance of electrical charge (i.e. electrons). Current (I) is the flow of electrons, however, electrons (since they are negative) flow in the opposite direction of the “current”.
Which is dangerous current or voltage?
An electrical current at 1,000 volts is no more deadly than a current at 100 volts, but tiny changes in amperage can mean the difference between life and death when a person receives an electrical shock.
What is the safe voltage for a human body?
Safe Voltage Levels The fundamental approach to protect against electric shock is to prevent contact with voltages that can cause a hazardous current through the body. Voltages above 30 Vrms or 42.2 volts peak or 60VDC are considered great enough to potentially cause a lethal electric shock to humans.
CAN 5000 volts kill you?
You could perhaps die from it. If you had a sustained 5,000 volt source, say at the electricity entrance into a factory, grabbing hold of that would do serious damage to you. That is more than the voltage used to electrocute people in prisons (yes, I know, not done any more, or exceedingly rarely).
Which voltage is dangerous?
Voltages over approximately 50 volts can usually cause dangerous amounts of current to flow through a human being who touches two points of a circuit, so safety standards are more restrictive around such circuits. In automotive engineering, low voltage is defined as voltage in range 30 to 1000 VAC or 60 to 1500 VDC.
Can 9 volts kill you?
To kill a person, an electrical shock has to pass through the heart causing arrhythmia. Even if it entered the body, a 9 volt current is not strong enough to cause arrhythmia. But also, it never actually enters the body.
What happens if the voltage is too high?
Voltage that is too high can cause premature failure of electrical and electronic components (e.g. circuit boards) due to overheating. There is a point where the voltage level supplied can be so high as to damage a motor but this level is far higher than that for electronics.
How many volts is 2 amps?
Equivalent Amps and Volts Measurements
| Current | Voltage | Power |
|---|---|---|
| 2 Amps | 17.5 Volts | 35 Watts |
| 2 Amps | 20 Volts | 40 Watts |
| 2 Amps | 22.5 Volts | 45 Watts |
| 2 Amps | 25 Volts | 50 Watts |
What is 30 amps in Watts?
The formula is 30 amps X 120 volts = 3,600 watts.
How many amps is 80 watts at 110 volts?
How do you convert watts to amps?
| Power | Current | Voltage |
|---|---|---|
| 80 watts | 6.667 amps | 12 volts |
| 90 watts | 7.5 amps | 12 volts |
| 100 watts | 8.333 amps | 12 volts |
| 110 watts | 9.167 amps | 12 volts |
How many amps is 1000 watts at 12v?
83 amps
How do you calculate 12v amps?
You don’t need to calculate anything for this as the current draw is already given in amps at 12 volts. You want to use a 12 volt 20 watt light bulb. To work out the amps you just divide 20 watts by 12 volts and you get 1.67 amps.
