Choke coil works on the principle of

Options

A. Transient current
B. Self induction
C. Mutual induction
D. Wattless current

Answer

**Step-by-Step Solution:**

1. **Understanding Choke Coil:**
- A choke coil is an electrical component that is used primarily in circuits to limit or suppress high-frequency alternating current (AC) while allowing low-frequency direct current (DC) to pass through.

2. **Functionality of Choke Coil:**
- In practical applications, such as in tube lights, choke coils are used to control the flow of electricity. They help in starting the lamp and regulating the current flowing through it.

3. **Principle of Operation:**
- The choke coil operates based on the principle of self-induction. When an alternating current passes through the coil, it creates a magnetic field around it. Any change in the current will induce a voltage in the coil itself, opposing the change in current due to Lenz's Law.

4. **Conclusion:**
- Therefore, the choke coil works on the principle of self-induction. This means that it generates an electromotive force (EMF) in response to changes in the current flowing through it.

5. **Correct Answer:**
- The correct answer to the question is that a choke coil works on the principle of self-induction.
