Key Stage 3
Meaning
A picture showing an analogue ammeter.
An ammeter is a measuring device used to measure electrical current.
About Ammeters
- Ammeters are added in series to a circuit to find the current flowing through the circuit.
- An ideal ammeter has zero resistance because otherwise adding an ammeter to a circuit would change the current.
- Ammeters can be analogue with a needle pointing to numbers on a dial or it can be digital with a number display.
 |
| An ammeter placed in series with a bulb. |
Key Stage 4

|
| To measure the current through bulb 1 the ammeter must be placed in series with bulb 1. | To measure the current through bulb 2 the ammeter must be placed in series with bulb 2. |
