a single phase is supplied with sinusoid voltage v(t)=200cos(377t).the resulting instantaneous power is p(t)=800+1000cos(754t-36.7). find
Q. Given that a silicon n-channel JFET has V P = 5 V and I DSS = 12 mA, check whether the device is operating in the ohmic or active region when v GS =-3.2 V and i D = 0.5 mA.
Q. Explain the construction of JFET? The basic construction of the p-channel JFET is shown in figure. The major part of the structure is the p-type material that forms the chan

3-phase 120 0 Mode VSI In 1200 mode VSI each thyristor conducts for 1200. At a time only thyristor one form upper group and another form group will conduct. Only th
Induction motors are often braked rapidly by a technique known as plugging, which is the reversal of the phase sequence of the voltage supplying the motor. Assume that a motor with
Q. Frequency-controlled induction-motor drives ? The converters employed for variable-frequency drives can be classified as: • Voltage-source inverter (which is the only one
