36.
A single phase half wave controlled rectifier circuit has a free wheeling diode. The load is a combination of R and L. The firing angle is a. The period of conduction of SCR and free wheeling diode respectively are
a < ωt < p and p < ωt < (2p + a)
a < ωt < p and p < ωt < 2p
a < ωt < (p + a) and (p + a) < ωt < 2p
a < ωt < p and p < ωt < (2p - a)
Answer: Option
Explanation:

SCR conducts from a to p and free wheeling diode from p to (2p + a).
