The physical quantity which having units ohm meter is - A)Specific resistance
- Specific Resistance is defined as "the resistance offered per unit length and unit cross-sectional area when a known amount of voltage is applied."
- The formula for specific resistance is - p = RA/l. In the formula - p is specific Resistance, R is Resistance, A is area and l is length.
- Resistance has unit ohm.
- Conductance has unit mho or siemens.
- Current density has unit ampere/metre².
