A 100-MVA, 14.4-kV, 0.8-PF-lagging, 50-Hz, two-pole, Y-connected synchronous generator has a perunit synchronous reactance of 1.1 and a per-unit armature resistance of 0.011.
(a) What are its synchronous reactance and armature resistance in ohms?
(b) What is the magnitude of the internal generated voltage EA at the rated conditions? What is its torque angle d at these conditions?
(c) Ignoring losses in this generator, what torque must be applied to its shaft by the prime mover at full load?

Suppose that a current x(t) = e^-0.5t for t > or equal to 0, and zero otherwise is applied to a discharged capacitor of capacitance C =1F at t = 0 sec. What would be the voltage in the capacitor at t= 1 seconds
Assume two cables have wire strands that are the same diameter and made of the same material. If one cable has 7 strands and another has 19 strands, which will have more resistance over a mile
pecify the value for R. What is the diode current with the load connected What is the increase resulting in the output votage when the load is disconnected What change results if the load resistance is reduced to 100ohms? To 75ohms To 50ohms
A person shuffling across a dry carpet can be approximately modeled as a charged 100-pF capacitance with one end grounded. If the person touches a grounded metallic object such as a water faucet, the capacitance is discharged
