Assertion (A): Power loss in a conductor of resistance P = I2R.

Reason (R): When a conductor is carrying current with current density J as a result of applied field E, then heat developed/m3/ second = JE.

  • A.Both A and R are true and R is correct explanation of A
  • B.Both A and R are true but R is not correct explanation of A
  • C.A is true but R is false
  • D.A is false but R is true
