7. A chopper feeding on RL load is shown in the figure, with V=200 V, R = 50, L 5 mH f = 1kHz, d = 0.5 and E = 0 V. Calculate a) Maximum and minimum values of load current. b) Average value of load current. c) RMS load current. TSS V Chopper FWD io E 1000002 H

If the load is connected to the generator thgrough an inductive line and the voltage at the load side is the same as the voltage at the terminals of the generator, which of the following must be true? O A. The reactive power is flowing from the generator to the load and from load to the generator at the same time. O B. The load is disconnected, and no power is delivered to the load. O C. The load has a poor power factor and it's absorbing too much reactive power. O D. None of the other choices are correct O E. The generator is unable to produce reactive power; therefore, the reactive power is flowing from the load to the generator.

A load has a leading power factor. a) Is it a capacitive or inductive load? b) Is the reactive power positive or negative?  c) Repeat for a load with lagging power factor

a. For the circuit shown in figure 2, determine the load impedance for maximum power transfer to the load. Assume 50 22 output resistance of the function generator. b. Calculate the maximum average power transferred to the load. c. If the load is purely resistive element, what will the resistance of the load be for maximum power transfer?
