What is a circuit?

Back

A circuit is a closed path through which electric current flows. It can be simple or complex.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where the components are connected in a single path, so the current flows through one component to get to the next.

Front

What is a parallel circuit?

Back

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

Front

What is volume?

Back

Volume is the amount of space an object occupies, measured in liters or cubic centimeters.

Front

What is a wire?

Back

A wire is a conductor that carries electrical energy from one point to another, such as from a battery to a light bulb.

Front

What is a light bulb?

Back

A light bulb is a device that converts electrical energy into light energy.
