A coil of inductance 
has an inductive reactance of 
in an AC circuit in which the effective current is 
. The coil is made from a super-conducting material and has no resistance. The rate at which power is dissipated in the coil is
A
0
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Coil has no resistance, only inductive reactance is present.
i.e. circuit is purely inductive power dissipated in purely inductive circuit is zero.
∴ rate at which power is dissipated in the coil 
.
