Question

To reduce current in an ac circuit,a choke coil is preferred over a resistance. This is so because

• A. choke coil is easier to design
• B. choke coil is cheaper
• C. choke coil consumer much less power
• D. the eddy currents produced in a choke coil quickly reduce the current in the circuit.

Answer 1

The correct option is D the eddy currents produced in a choke coil quickly reduce the current in the circuit.

Answer D
choke coil acts as an inductor, with the eddy currents produced in a choke coil quickly reducing the current in the circuit due to self induction.
