The potential difference across the lamp can be increased without changing the mains supply by decreasing the length of the wire and increasing the thickness of the wire.

Increasing the potential difference across a lamp

The potential difference across a lamp can be increased without changing the mains supply by decreasing the resistance of the wire.

The two ways include;

  • decreasing the length of the wire
  • increasing the thickness of the wire

Thus, the potential difference across the lamp can be increased without changing the mains supply by decreasing the length of the wire and increasing the thickness of the wire.
