1
Q
How do you measure electric current
A
using an ammeter
2
Q
What is electric current measured in?
A
amps or A or amperes
3
Q
where in the circuit is the ammeter placed?
A
in between the batteries and the bulb
4
Q
How do you measure potential difference?
A
by a voltmeter
5
Q
What is potential difference measured in?
A
Volts or V
6
Q
Where do you put the voltmeter?
A
across something in a circuit like across a bulb
7
Q
What do potential difference ratings tell you in a battery?
A
the potential difference it will supply
8
Q
What does a bulb’s rating tell you?
A
The maximum potential difference that you can safely put across it
