Electricity and 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 uninterrupted.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected end-to-end, 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 conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as metals like copper and 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, wood, 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 light bulb?

Back

A light bulb is a device that converts electrical energy into light energy when current passes through it.

Front

What happens when a circuit is incomplete?

Back

When a circuit is incomplete, the flow of electric current stops, and devices like light bulbs will not work.

Front

What is resistance in an electrical circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current, affecting how much current can flow.
