Question

The ratio of latching current to holding current of SCR

• A. is always more than one
• B. always depends on gate current
• C. is always less than one
• D. is always equal to one

Hint:

SCRs: \( I_L>I_H \), so their ratio is always more than one.

Answer 1

The Correct Option is A

For SCRs:
- Latching Current is the minimum current to turn it ON.
- Holding Current is the minimum current to keep it ON. \[ I_L>I_H \Rightarrow \frac{I_L}{I_H}>1 \]
