Electric circuits quick check

1 answer

1. What is an electric circuit?

An electric circuit is a closed loop pathway through which an electric current flows.

2. What are the components of an electric circuit?

The components of an electric circuit include a power source (such as a battery), conductors (wires), load (such as a light bulb or motor), and a switch (optional).

3. What is the purpose of a switch in an electric circuit?

A switch in an electric circuit is used to control the flow of electricity by opening or closing the circuit. It can turn a device on or off.

4. What is resistance in an electric circuit?

Resistance is the measure of how much a material or device opposes the flow of electricity. It is measured in ohms (Ω).

5. How is resistance calculated in a circuit?

Resistance can be calculated using Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I): R = V/I.

6. What is the difference between a series and parallel circuit?

In a series circuit, all components are connected in a single loop, so there is only one pathway for the current to flow. In a parallel circuit, components are connected in multiple branches, creating multiple pathways for the current to flow.

7. What happens if one component in a series circuit fails?

If one component in a series circuit fails, it can cause the entire circuit to stop functioning because the current cannot flow past the broken component.

8. What happens if one component in a parallel circuit fails?

If one component in a parallel circuit fails, the other components will still receive power and continue to function because they are connected in separate branches.
