- @answer 2
- @feedback wrong
- No, it is the negative charge that is moving -
- carried by electrons which are tiny negatively
- charged particles that can move through the
- metal wire easily.

-
- @feedback correct
- Yes, it is the negative charge that is moving -
- carried by electrons which are tiny negatively
- charged particles that can move through
- the metal wire easily.

- The cell pumps electrons carrying a negative charge to the negative
- terminal which in turn push the electrons in the wire round the circuit.
- This is why the lamp lights up immediately you press the switch.
