If the cathode of an SCR is made positive with respect to the anode & no gate current is applied then
  • a)
    all the junctions are reversed biased
  • b)
    all the junctions are forward biased
  • c)
    only the middle junction is forward biased
  • d)
    only the middle junction is reversed biased
Correct answer is option 'C'. Can you explain this answer?

The device is in the reverse blocking state (3rd quadrant) & only the middle junction is forward biased whereas other two are reversed biased.

Hence Option (C) is correct

, the device will not conduct current. This is because the SCR is designed to only conduct current when a positive voltage is applied to the anode with respect to the cathode. When the cathode is made positive, the SCR will remain in its non-conducting state, and no current will flow through the device.
