I need the answer as soon as possible Q5/ Two thyristors are connected in parallel to share a total load current of I, = 800A. The on-state voltage drop of one thyristor is Vr= 1.5 V at 300 A and that of otherthyristors is V2 1.8 V at 300 A. Determine the values of series resistances to forcecurrent sharing with 7.5% difference. Total voltage v = 4V.

According to the question we have to calculate the values of series resistance.

Answered: Q5/ Two thyristors are connected in…

You are working as an electrician in a large steel manufacturing plant, and you are in the process of doing preventive maintenance on a large DC generator. You have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer.

FACTS: AC-DC converters take the AC power from wall outlets and convert it to unregulated DC. These power supplies include transformers that change the voltage of the AC that comes through wall outlets, rectifiers to save it from AC to DC and a filter that removes noise from the peaks and troths of the AC power waves.The DC-to-AC Converters are used to charge the batteries in the vehicles. These circuits are mainly used for driving low-power AC motors and are used in a solar power system. The DC to AC converters can be used in dc transmission lines for transmitting power to loads. QUESTION: What do you think is the main reason why we have AC power in our outlets instead of DC power? Explain your answer.
