MCQ
The coil of choke in a circuit
- AIncreases the current
- ✓Decreases the current
- CDoes not change the current
- DHas high resistance to $dc$ circuit
✓
Answer
Correct option: B.
Decreases the current
b
(b) In a circuit with a.c,source, choke coil which is essentially an inductor with high reactance, is used to decrease the current without loss of energy.No heat is generated so no loss of energy. When we use resistance to reduce current, there is loss of electrical energy in the form of heat generated.
