What is a Component?
A part of a circuit eg a battery, motor, lamp, switch, or wire.
What is a circuit?
An electrical circuit is made up of components, which are connected together using wires.
what is a current?
Current is a flow of charges. It is measured in amps (A).
What is a lamp?
A component that produces light when current flows through it.
What is a motor?
A device that spins when current flows through it.
What is a cell?
Cells provide energy that enables electrons to flow through wires and components when connected to an electrical circuit. Cells can be connected together to form batteries.
What is a battery?
A battery is made of two or more cells connected together.
What is an ampere or amp(A)?
The unit of measurement of current. Ampere is often shortened to amp.
What is an ammeter?
A device used to measure current. Ammeters are connected in series with components.
What is used to measure current?
An ammeter.
What is used to measure potential differences?
An voltmeter.
Which component provides power to the circuit?
A cell, battery (combination of cells), or power supply provides power to the circuit.
What is used to measure current?
An ammeter.
How is an ammeter connected to a circuit?
In series, anywhere in the circuit.
How is a voltmeter connected to a circuit?
In parallel, with one lead on each side of the component.
