Electricity and Circuits

Front

What is a switch in an electrical circuit?

Back

A switch is a component that can open or close a circuit, thereby starting or stopping the flow of electricity.

Front

What materials are considered conductors?

Back

Conductors are materials that allow electricity to flow through them 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, glass, or wood.

What happens in a series circuit if one bulb burns out?

Back

In a series circuit, if one bulb burns out, the entire circuit is broken, and all bulbs will go out.

Front

What happens in a parallel circuit if one bulb burns out?

Back

In a parallel circuit, if one bulb burns out, the other bulbs will continue to light because they have separate paths for electricity.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, so there is only one path for current. In a parallel circuit, components are connected across common points, providing multiple paths for current.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, which drives the flow of current.

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 current in a circuit, measured in ohms (Ω).
