Answer / arvind

the basic difference between the two is
thyristor is a switching device which requries a gate pulse
to start whereas capacitor is a storage device which store
the energh and it does not requries a gate pulse to start.

Answer / om prakash

thyristor is a switching device which requires a gate pulse
(barrier voltage)
to start. It is use only for switching

Capacitor is a storage device which store
the energy and it does not requires a gate pulse to start.
When capacitor stored energy than called charged .

If R and Y terminals are short circuited,then power will cut. we all know that power cannot be stored.what will happen to already generated power at power station?
