Question

If the reactance of a choke coil is $X_L$ and its resistance is $R$ then

• A. $X_L=R$
• B. $X_L>>R$
• C. $X_L<<R$
• D. $X_L=\propto$

Answer 1

Answer: (B)

$X_L>>R$

Choke coil is combination of resistance and inductor.
Which is used to pass dc current through Circuit properly and to attenuate AC current flow in circuit.
For this purpose a inductor of very large value and a low resistance is used so that this can resist AC current more.
so reactance (resistance due to inductor ) of choke coil will be much more than resistance.
