The Circuit Review

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow through it, consisting of a power source, conductors, and a load.

Front

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

Back

In a series circuit, components are connected end-to-end, so the current flows through each component one after the other. In a parallel circuit, components are connected across the same voltage source, allowing current to flow through multiple paths.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber or glass.

Front

What is a switch in a circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What is a load in a circuit?

Back

A load is any device that uses electricity to perform work, such as a light bulb or a motor.

Front

What happens when a circuit is open?

Back

When a circuit is open, the flow of electricity is interrupted, and the devices connected to the circuit do not operate.

Front

What happens when a circuit is closed?

Back

When a circuit is closed, electricity can flow freely, allowing devices connected to the circuit to operate.

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, measured in volts (V). It is what pushes electric current through the circuit.

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (A). It represents how much electricity is flowing.
