Physics Question on Electromagnetic induction
A choke coil should have
A
high resistance and low inductance
B
high resistance and high inductance
C
low resistance and high inductance
D
low resistance and low inductance
Answer
low resistance and high inductance
Explanation
Solution
A choke coil should have high inductance and low resistance. This is done to reduce the current in an A.C. circuit. The high inductance is used in place of a high resistance because the inductance does not consume power, and thus no energy is lost as heat.
