What is a circuit?

Back

A circuit is a closed path through which electric current flows. It consists of a power source, conductors, and a load.

Front

What are conductors?

Back

Conductors are materials that allow electric current to flow through them easily, such as copper and aluminum.

What are insulators?

Back

Insulators are materials that do not allow electric current to flow through them easily, such as rubber and glass.

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 or junctions, allowing current to flow through multiple paths.

Front

What is a switch?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What is a battery?

Back

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

Front

What is a load in a circuit?

Back

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

What is voltage?

Back

Voltage is the measure of electric potential difference between two points in a circuit, often referred to as electrical pressure.

Front

What is current?

Back

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