A: TRIAC will break over and conduct at a certain if a certain voltage is reached. That voltage depends on all different triacs devices
forward breakover voltage is slightly smaller than reverse breakdown voltage
ZENER DIODE IS MADE TO REVERSE BREAK OVER AT A CERTAIN VOLTAGE the break over knee is not exactly sharp especially in low voltage zeners. and p-n means positive and negative junction
Due to the physical construction and size of the resistor, at a certain voltage, the insulation will break down and the applied voltage will arc over. This is generally bad. Operating the resistor within its voltage rating will prevent this failure mode.
For power control of inductive load.They can be successfully used for resistive load as well.
A Thyrector is essentially two zener diodes connected back-to-back in opposing polarity which means it will not conduct until an over-voltage above its break-down voltage rating occurs. This is used to trap voltage spikes and suppress them.
If the MT2 voltage exceeds VDRM such as might occur during severe and abnormal mains transient conditions, MT2-MT1 leakage will reach a point where the triac will spontaneously break over into conduction.

It is stated that one of the voltage is greater in thyristor whether it be forward breakover or reverse breakdown voltage. It is also stated that the greater of the 2 voltages in thyristor is the forward breakover voltage.

Medium voltage is over 1000 v, high voltage is over 45 kV.
Upping the voltage is the easiest method to do but you have to be careful of the insulation rating of the wire in the electromagnet coil. As the voltage goes up so does the current and the heat produced by this action. By over exceeding the voltage rating of the wire this will cause the insulation to break down and short the coil out.
Voltage drop due to the resistance present in the series circuit causes voltage split over a series circuit.
Less likelihood of electrocotion.
silicon has a wider bandgap than germenium .silicon jeakage current small, easily available then Ga and break down voltage is more. knee voltage of si is 0.7and Ga is having 0.3then Si is very useful.
