Choke coil is used to control

Question

Choke coil is used to control (A) AC (B) DC (C) Both AC and DC (D) Neither AC nor DC

Tardigrade Admin · Accepted Answer

The choke coil can be used only in AC circuits and not in DC circuits because for DC (ω=0) the inductive reactance XL=ω L of the coil is zero, only the resistance of the coil remains effective which too is almost zero.

Both AC and DC

Neither AC nor DC

The choke coil can be used only in AC circuits and not in DC circuits because for DC $(ω = 0)$ the inductive reactance $X_{L} = ω L$ of the coil is zero, only the resistance of the coil remains effective which too is almost zero.
