A 400V,50Hz,Y-connected, 4-pole,three-phase wound rotor induction motor, the rotor circuit is Y-
connected with R2=0.1, X2= 0.8 Q/ph .The measured e.m.f between two slip rings at 1440 rpm is
165 V. If the total stator losses are 650 W,find:airgap power, rotor copper loss, input power, developed
(or gross) mechanical power, output power, efficiency, if friction and windage losses are 377W?
consider the circuit below. Assume it uses ideal diodes with the details specified above. the left side of the circuit is basically a wheatstone bridge, hooked to the right side, which is a differential op amp. a) what is the voltage between junctions "A" and "B" if R2 is 201 ohms? b) what are the minimum and maximum values of R2 can be without the op amp hitting saturation?remember that for the diodes to be ideal you they have to have a turn on voltage of 0.6 volts.
