The power factor of a good choke coil is

Question

The power factor of a good choke coil is (A) nearly zero (B) exactly zero (C) nearly one (D) exactly one

Tardigrade Admin · Accepted Answer

For a good choke coil inductance is very high and resistance is very low. Therefore, power factor = cos φ = cos 90o=0 Therefore, power factor for a good choke coil is nearly zero.

Q. The power factor of a good choke coil is

nearly zero

exactly zero

nearly one

exactly one

For a good choke coil inductance is very high and resistance is very low. Therefore, power factor $= cos ϕ = cos 90^{o} = 0$ Therefore, power factor for a good choke coil is nearly zero.
