Question

Define 1 ohm of resistance and resistivity of a conductor

Answer 1

1 Ohm is the resistance of a conductor through which 1 ampere of current flows with 1 volt of electric potential difference applied across it.

1 Ohm metre may be defined as the resistivity of a material whose resistance is 1 ohm, length is 1 metre and area of cross section is 1 metre square.

Hope it helped :)

Answer 2

Answer:

One ohm of resistance can be defined as the resistance across a conductor when 1 ampere of current flows through it due to 1 volt of potential difference.

The ability of a conductor of resistance 1 ohm of one metre in length with the cross section area of 1 metre square is known as 1 ohm metre of resistivity.
