Q. The voltage across the circuit in the figure, and the current through it, are given by the following expressions:
๐ฃ(๐ก) = 5 โ 10 cos(๐๐ก + 60ยฐ) V
๐(๐ก) = 5 + ๐ cos(๐๐ก) A
where ๐ = 100 ๐ radian/s. If the average power delivered to the circuit is zero, then the value of ๐ (in Ampere) is ________

Ans: 10
