Answer:
choke coil is preferred to a resistor in an alternating current circuit.
Explanation:
a choke coil is an inductance which provides reactance (XL)which is equal to 2FL ,where f is the frequency of a.c.source and L be the self inductance of the coil .this reactance is helps to control the current
