How can we protect SCR from thermal conditions _____________?
Correct answer: B. Using heat sink.
- A. Use of snubber circuit.
- B. Using heat sink.
- C. Using CB and fuse.
- D. Using equalizing circuit
Explanation
Thermal protection is obtained by conducting heat away from the SCR, and a heat sink provides the required low-resistance path to the surroundings. Snubbers address voltage transients, while fuses and circuit breakers mainly provide overcurrent protection.
