A thyristor is basically________?
Correct answer: A. PNPN device
- A. PNPN device
- B. A combination of diac and triac
- C. A set of SCRs
- D. A set if SCR,diac and triac
Explanation
A thyristor has four semiconductor layers arranged as P-N-P-N, giving it three junctions. The other options describe combinations of separate devices rather than the basic thyristor structure.
