A thyristor if conducting will have a very small voltage drop across if not then the rail voltage will be evident across the device
A thyristor is a semiconductor device which acts as a switch.
No because a mosfet does not work the same as a thyristor. In a thyristor the current flows even when the gate pulse is removed, until the current stops. That is not the case for a FET.
There are more than two conditions that can make a thyristor conduct, but the general (functional) ones are: 1) positive voltage form anode to cathode, and 2) a positive voltage on the trigger input (referenced to the cathode) for a standard polarity thyristor. Other conditions can be: A) Anode-Cathode Voltage exceeding thyristor witholding voltage. B) Overtemperature of the thyristor chip C) Faulty thyristor (can be caused by overloads)
A thyristor, also known as a silicon controlled rectifier, is a diode that can be turned on by application of a small gate voltage.
thyristor can be turned off only by reducing the anode current belaw a certain value called holding current by abdullahi yusuf gedi
A forward bias A positive pulse to the gate of the thyristor.

not a clue a A: It all depends on the thyristor. There are no calculation involved not until you look up the thyristor specifications and decide on the load of the thyristor then you may calculate or more likely choose.
The turn off and turn off mechanism of a thyristor can be best explained by the gate turn-off thyristor. The thyristor uses the reverse bias mechanism.

Thyristor is a kind fast acting switch. These are fully controlled switches
Well it is probably a name that doesn't have any specific meaning.Or they meant confirm rather than comfirm.
The term "Forced commutation" is used when a thyristor is turned off using external components. If a thyristor is used in a DC circuit, when first turned on, it will stay on until the current goes to zero. To turn off the thyristor it is possible to use a Forced commutation circuit. The circuit creates a reverse voltage over the thyristor (and a small reverse current) for a short time, but long enough to turn off the thyristor. A simple circuit consist of a precharged capacitor and a switch (e.g. another thyristor) parallel to the thyristor. When the switch is closed, the current is supplied by the capacitor for a short while. This cause a reversed voltage over the thyristor, and the thyristor is turned off.
