A) nearly zero
B) exactly zero
C) nearly one
D) exactly one
Correct Answer: A
Solution :
For a good choke coil inductance is very high and resistance is very low. Therefore, power factor\[=\cos \phi =\cos {{90}^{o}}=0\] Therefore, power factor for a good choke coil is nearly zero.You need to login to perform this action.
