    Hi guys, i came across the turning on process of thyristor scr and i am pretty confuse about what my lecturer says, he says that when a gate current is applied the depletion region of the j2 will be increased and this causes regenerative effect and large anode current to flow

    But i was confused, doesnt the increased depletion region impede current flow from anode to cathode?
