"The Circuit"

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 common points, 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 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.

Front

What is resistance?

Back

Resistance is the opposition to the flow of electric current, measured in ohms (Ω). It determines how much current will flow for a given voltage.

Front

What is a battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to provide power to a circuit.

Front

What is a load in a circuit?

Back

A load is any component in a circuit that consumes electrical energy, such as a light bulb or a motor.
