explain the transmission of electric power from generating station to home
why is the earth wire pin thicker & longer than that of pins of live&neutral wire in a plug?
An electric heater of resistance 8 ohms draws 15A from the service mains 2 hrs. Calculate the rate at which heat is developed in the heater.
if a current is flowing therfore earth and neutral wire is at xero potential now why only fuse melts only with earth wire when there is neutral is at xero potential...
