Leakage current flows through the thyristor in_________?
Correct answer: C. both forward and reverse blocking mode
- A. forward blocking mode
- B. reverse blocking mode
- C. both forward and reverse blocking mode
- D. forward conduction mode
Explanation
A thyristor carries only leakage current in either blocking condition: forward blocking with the anode positive, or reverse blocking with the anode negative. In forward conduction, the current is no longer called leakage current.
