an additional wire used along with live and neutral wire is:
with the increase in temperature the resistance of pure
metals:
If 2 joules of energy is required to transfer one coulomb of
charge from one point to another, the potential difference between these points
will be:
When a potential of 10 volt is applied across a conductor, a
current of 5 miliampere flows through it, the resistance of the conductor will
be:
