Q. Calculate the total heat dissipated in a resistor of 44 Ω when 0 A current flows through it.

(A) 0 w
(B) 2 w
(C) 1.5 w
(D) .3 w
Correct : Option (A)

Explanation: 
 the resistor is a linear element. it only absorbs real power and dissipates it in the form of heat. the voltage and current are in the same phase in case of the resistor so the angle between v & i is 90°.
