the earth wire is connected together with the live wire terminal. when the plug is connected to the socket, what will happen to the appliance? Relevant Equations: na there are 4 options. a) the fuse blows b) the appliance becomes live c) the appliance catches fire d) the appliance doesn...
The neutral wire is connected to an earth ground. So, it may also divert unstable or excess current, as well as completing the circuit. But the ground wire is specifically installed only to “ground,” or send to earth, any unstable or excess current. ...
