The mathematical form of ohm's law is:

Correct answer: D. I = V/R

  • A. l = VR
  • B. R = VI
  • C. I = R/V
  • D. I = V/R

Explanation

OHM'S LAW STATEMENT: The magnitude of the current in a conductor is proportional to the applied voltage as long as the temperature of the conductor is kept constant.MATHEMATICAL FORM OF OHM'S LAW: I∝V I=kV (k=1/R) I=V(1/R) or I=V/R or V=IR

About Current Electricity

Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
