Key Stage 3

Meaning

 
A picture showing an analogue voltmeter.

A voltmeter is a measuring device used to measure the potential difference between two points in a circuit.

About Voltmeters

Voltmeters are added in parallel to components in a circuit to find the potential difference between two points.
An ideal voltmeter has infinite resistance because otherwise adding an voltmeter to a circuit would change the Potential Difference between two points.
Voltmeters can be analogue with a needle pointing to numbers on a dial or it can be digital with a number display.
 
A voltmeter placed in parallel with a bulb.

Key Stage 4

Meaning

A voltmeter is a measuring device used to measure the potential difference between two points in a circuit.

About Voltmeters

Voltmeters are added in parallel to components in a circuit to find the potential difference between two points.
An ideal voltmeter has infinite resistance because otherwise adding an voltmeter to a circuit would change the potential difference between the two points.
Voltmeters can be analogue with a needle pointing to numbers on a dial or it can be digital with a number display.
Using a voltmeter on components in series.
 
 
To measure the potential difference across bulb 1 the voltmeter must be placed in parallel with bulb 1. To measure the potential difference across bulb 2 the voltmeter must be placed in parallel with bulb 2.
 
 
Using a voltmeter on components in parallel.
 
 
To measure the potential difference across bulb 1 the voltmeter must be placed in parallel with bulb 1. To measure the potential difference across bulb 2 the voltmeter must be placed in parallel with bulb 2.
 
 
In this case both voltmeters will give the same measurement because the components themselves are in parallel.
