Q. Radio frequency choke has core of

AFMCAFMC 2004Alternating Current

Solution:

Chokes are inductances that isolate AC frequency current from certain areas of a radio circuit. Chokes depend upon the property of self-inductance for their operation. They are used to block alternating current while passing direct current. Radio frequency coil ie, a low frequency choke coil is made of insulated copper wire wound on a soft iron core.
