Physics Question on Electromagnetic induction
A choke coil has
A
low inductance and high resistance
B
high inductance and low resistance
C
low inductance and low resistance
D
high inductance and high resistance
Answer
high inductance and low resistance
Explanation
Solution
A choke has high inductance and low resistance. A choke is an Inductoror a non-resistive device, in which the large inductance value of the coil decreases the current in the circuitdrastically. The smaller resistance of the coil does not allow consumption of any form of powereven in the form of heat. Thus, the power loss is highly minimized. For applications where power is to be saved, the high inductance and low resistance choke is used.
