What is an electric circuit?

Back

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

Front

What happens in a series circuit when one component fails?

Back

In a series circuit, if one component fails, the entire circuit is broken and all components stop working.

Front

What is the purpose of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

What is resistance in an electrical circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms.

Front

What is the unit of electric current?

Back

The unit of electric current is the ampere (A).

Front

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

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points.

Front

What is a conductor?

Back

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

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current, such as rubber or glass.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R): V = I × R.

Front

What is a load in an electrical circuit?

Back

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