Answer

Explanation:A switch in the electrical circuit is always connected to the live wire so that the socket/appliance is not live when it is switched off. A fuse is usually a thin piece of wire that will melt and break the circuit if too large a current flows through it.

  • Explanation:
  • The fuse is connected to the live wire so that the appliance will not become charged (have a potential difference of 230 V) after the fuse has melted due to excessive current.
