A) ac
B) dc
C) Both ac and dc
D) Neither ac nor dc
Correct Answer: A
Solution :
The choke coil can be used only in ac circuits, not in dc circuits, because for dc (w = 0) the inductive reactance \[{{X}_{L}}=\omega L\]of the coil is zero, only the resistance of the coil remains effective which too is almost zero.You need to login to perform this action.
