For a 45-kVA, three-phase, wye-connected, 220- V synchronous machine at rated armature current, the short-circuit load loss (total for three phases) is 1.80 kWat a temperature of 25°C. The dc resistance of the armature at this temperature is 0.0335 per phase. Compute the effective armature ac resistance in per unit and in ohms per phase at 25°C.
HOW ARE FLIP-FLOPS USED IN BINARY COUNTERS
What is resistivity? Resistivity of a material may be explained as the resistance of the material having unit length and also unit cross sectional area. Unit of it is ohm-m.
Q. An integrator with positive voltage on a noninverting input is shown in Figure. Sketch v o for 60 ms after S has been opened.
Q. What do you mean by Magnetic circuits? A magnetic circuit provides a path for magnetic flux, just as an electric circuit provides a path for electric current.Magnetic circui
Based upon the following inputs, propose the optimal course of action for this venture: Probability of success: 30%; probability of failure: 30%; base case probability: 40%
Q. Write a control word for counter 1 of 8253 / 8254 that selects following options: load least significant byte only, mode 5 of operation and binary counting. Then write an inst
A 300 km, 3-phase, 50Hz transmission line has spacing as shown in Figure. Each phase of the line consists of a bundle of three conductors. (a) Find the total per-phase inductanc
Modern complex systems are normally constructed by interconnecting sub-units. Therefore the systems engineer is often not too concerned about the details of what is inside these
