What does the flashlight represent?
Earth — The small globe represents the Earth and a flashlight represents the Sun.
Why is a flashlight important?
A good emergency kit and an emergency plan are vital for survival. Flashlights are an important part of any kit as they can give light when no other source is available in a manner that’s much safer than exposed candles. After a storm or other disaster strikes, power might be out for hours or even days.
Why do you think the flashlight was used to represent the sun?
Flashlight is represent as a Sun because of this light and bright like a Sun. 2. Shadows give us some information about shapes of objects.
Is a flashlight a series or parallel circuit?
For example, the circuits in flashlights are usually series circuits. The charge flows through one battery, through the next, through the bulb, and back to the first battery. The flashlight is brighter than it would be if its circuit contained only a single battery.
Is a flashlight An example of a series circuit?
Many people do not know that a flashlight is a simple series circuit.
What is the disadvantage of connecting cells in series in a flashlight?
Disadvantages: If one point breaks in the series circuit, the total circuit will break. As the number of components in a circuit increases, the circuit resistance will be increased too. If there is a break in the circuit, the current is able to pass through the circuit through different paths.
Is series better than parallel?
The two bulbs in the parallel circuit are powered by the same battery. The bulbs in the parallel circuit will be brighter than those in the series circuit. If one loop is disconnected, the other remains powered, which is an advantage to the parallel circuit.
What three things make up a complete circuit?
Every circuit is comprised of three major components:
- a conductive “path,” such as wire, or printed etches on a circuit board;
- a “source” of electrical power, such as a battery or household wall outlet, and,
- a “load” that needs electrical power to operate, such as a lamp.
Does series and parallel connections at home really matter?
Answer: A series circuit is a Voltage Divider. A parallel circuit avoids this problem. This is why the bulbs in the parallel circuit will be brighter than those in the series circuit.
Why do houses use parallel circuits?
Parallel circuits are used in homes because loads can be operated on their own. For example, if a series circuit was used, the lights would be dimmer with the addition of more lights. The load has the full power of the circuit when using a parallel circuit instead of a series circuit.
What is advantage of series circuit?
The biggest advantage of a series circuit is that you can add additional power devices, usually using batteries. This will greatly increase the overall force of your output by giving you more power. The second disadvantage is that the more components there are in a series circuit, the greater the circuit’s resistance*.
What are two safety features of a house circuit?
Several safety features are built into modern electric circuits and devices. They include three-prong plugs, circuit breakers, and GFCI outlets. Following safety rules can reduce the risk of injury or fire from electricity.
What are the electrical safety devices used at home?
Here are the 5 electrical safety devices that you should have installed in your home:
- Fuses.
- Ground Fault Circuit Interrupters.
- Arc Fault Circuit Breakers.
- Surge Protectors.
- Tamper Proof Receptacles.

Which electrical safety device is appropriate?
Circuit breakers are often considered safer since the user can’t as easily disable them (like putting the wrong size fuse in place). Circuit breakers functionally open a switch which turns off all the electrical current before the excess electrical current can start a fire.
