Electricity Unit Day 2

Front

What is electricity?

Back

Electricity is a form of energy resulting from the flow of electric charge, typically through conductors.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source to a device and back.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as metals like copper.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber or plastic.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What does a lightbulb do in a circuit?

Back

A lightbulb transforms electrical energy into radiant energy (light) and thermal energy (heat).

Front

What is the function of wires in a circuit?

Back

Wires allow the flow of electricity between different components of the circuit.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected one after another, while in a parallel circuit, components are connected across common points.

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 resistance in an electrical circuit?

Back

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