The Programmable Unijunction Transistor (PUT) turns on & starts conducting when the

(a) gate voltage exceeds anode voltage by a certain value

(b) anode voltage exceeds gate voltage by a certain value

(c) gate voltage equals the anode voltage

(d) gate is given negative pulse w.r.t to cathode

I had been asked this question in homework.

I need to ask this question from Other Thyristor Members-1 topic in chapter Power Electronics Devices of Power Electronics

The correct choice is (b) anode voltage exceeds gate voltage by a certain value

For explanation I would say: The device only starts to conduct when the forward anode to cathode voltage exceeds the applied gate to cathode voltage.
