Science Revision - Electricity

Question 1

Electricity

Answer 1

A flow of charged particles.

Question 2

Current

Answer 2

An electrical flow caused when electrons move around a circuit and carry electrical energy from one place to another place.

Question 3

Series Circuit

Answer 3

A circuit that only has one pathway. If one part of the circuit is broken, the whole circuit will break.

Question 4

Parallel Circuit

Answer 4

A circuit that has multiple pathways. If one of the pathways is broken, the rest of the circuit will continue working.

Question 5

Cell

Answer 5

A single unit of device that converts chemical energy into electrical energy.

Question 6

Battery

Answer 6

A collection of cells that converts chemical energy into electrical energy.

Question 7

Switch

Answer 7

A component in a circuit that can connect or break the circuit to control whether electricity flows.

Question 8

Resistance

Answer 8

A measurement of how difficult it is for current to flow.

Question 9

Resistor

Answer 9

The part of an electrical circuit that resists, or limits, the power of an electrical current in a circuit.

Question 10

Short Circuit

Answer 10

An electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance.
