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 is the difference between an open circuit and a closed circuit?

Back

An open circuit has a break in the path, preventing current from flowing, while a closed circuit allows current to flow continuously.

Front

What happens when a switch is closed?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and powering devices like lamps.

Front

What happens when a switch is open?

Back

When a switch is open, it breaks the circuit, stopping the flow of electricity and turning off devices.

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 does not allow electric current to flow through it easily, such as rubber or plastic.

Front

What is a battery?

Back

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

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected in a single path, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across common points, allowing multiple paths for current to flow.

Front

What is a load in an electric circuit?

Back

A load is any device that uses electrical energy, such as a light bulb, motor, or heater.
