Q. A 6.6-kV line feeds two loads connected in parallel. Load A draws 100 kW at 0.6 lagging power factor, and load B absorbs 100 kVA at 0.8 lagging power factor.
(a) For the combined load, calculate the real power, reactive power, volt-amperes, and line current drawn from the supply.
(b) If the power factor on the supply end is to be unity, determine the value of the capacitance to be placed across the load if the frequency of excitation is 60 Hz.
A step-down transformer has primary turns Np = 100; secondary turns Ns = 10; primary winding resistanceRp = 100 ?; secondary winding resistance Rs = 2 ?. Assume that there is no l
Q. A six-pole, double-layer dc armature winding in 28 slots has five turns per coil. If the field flux is 0.025 Wb per pole and the speed of the rotor is 1200 r/min, find the value
A signal stands for 0110 with positive logic in which low stands for 0 and high stands for 1. If negative logic (in which low stands for 1 and high stands for 0) is used, what digi

Q. The truth table for F(A,B,C) = Mi (0, 1, 6, 7) is as follows: (a) Express F in a canonical product-of-sums form. (b) Minimize F in a POS form and obtain a possible re
Note, the armature current is produced in pulses as the armature rotates under the poles, so the torque also pulsates. This can give rise to extra wear on bearings and the engin
