Q: Ohm-m is unit of…….?
  • A. Resistivity
  • B. Electric current
  • C. Charge
  • D. Resistance
Correct Answer: Option A - The S.I. unit of electrical resistivity is Ohm-meter. Resistivity is the resistance offered by an object per unit length and per unit cross-sectional area at a specified temperature. The Ohm (symbol : Ω) is the S.I. unit of electrical resistance, named in honor of German physicist Georg Simon Ohm.
