Electrical Circuits

Front

What is voltage?

Back

Voltage is the measure of electrical potential difference between two points in a circuit. It is what pushes electric current through a circuit.

Front

What is current?

Back

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

Front

What is resistance?

Back

Resistance is the opposition to the flow of electric current, measured in Ohms (Ω).

Front

What is an electrical conductor?

Back

An electrical conductor is a material that allows electricity to flow through it easily, such as copper or aluminum.

Front

What is an electrical insulator?

Back

An electrical insulator is a material that does NOT let electricity pass through it, such as rubber or glass.

Front

What is a series circuit?

Back

A series circuit is a type of circuit that has only one path for electricity to flow.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit that has multiple paths for electricity to flow.

Front

What happens when a switch is closed in a circuit?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and power devices like bulbs or buzzers.

Front

What is a battery?

Back

A battery is a device that stores electrical energy and provides voltage to a circuit.

Front

What is a light bulb?

Back

A light bulb is an electrical device that produces light when electricity flows through it.
