Electric Circuits

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What happens when a circuit is complete?

Back

When a circuit is complete, electricity can flow through it, allowing devices like bulbs to operate.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it, completing the circuit.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it, preventing current from passing.

Front

What is the role of a switch in a circuit?

Back

A switch controls whether an electric device is ON or OFF by opening or closing the circuit.

Front

What occurs when a switch is closed?

Back

When a switch is closed, the circuit is complete, allowing current to flow and devices to operate.

Front

What occurs when a switch is open?

Back

When a switch is open, the circuit is broken, and charges cannot flow.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, so current flows through each component. In a parallel circuit, components are connected across common points, allowing current to flow through multiple paths.

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, driving the flow of current.

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (A).
