Q95

An ideal thyristor is driving an R-L load of impedance Z. Input AC voltage Vs = Vmsinωmt. If thyristor if fired at an input phase angle of 90°. What will be the output voltage and output current across R-L load as the instant of firing?

A.
Output voltage is Vm and output current is Vm/Z
B.
Output voltage and output current are both zero
C.
Output voltage is zero and output current is delayed by an angle 90°
