A single phase 50 Hz source supplies power with the impedance of0.185 + j0.321 ohms. The terminal voltage of the motor is 230 V.The power drawn by the motor is 5 kW at a power factor of 0.7lagging, Calculate the following:a) magnitude of the voltageb)power lost in the distribution linec)total ipedance for the motor
The magnetic field produced in the air gap of an induction motor by the stator windings is given by B=Bm cos(wt-2theta) in which theta is angular displacement in the counterclockwise direction as illustrated.
The charge is release from rest and accelerate through a potential difference of 100000v. (a) Find the speed of the sphere after the acceleration. (b) if the sphere (which is already up to its max)is fired directly at a fixed (can't move) charge q..
Explain the process of processor development
A small circular parabolic reflector, often referred to as dish, is now being advertised as a TV antenna for direct broadcast. Assuming the diameter of the antenna is 1 meter, the frequency of operation is 3 GHz
Determine the HV-side fuses needed to protect a 3x140kVA, 12470/208 YNyn0 distribution transformer bank. Show and explain step by step the procedure you employ to solve this question. Use the type K and type T fuse curves
Find the sample space for the experiment: Drawing bolts from a lot of 20, containing one defective D, until D is drawn, one at a time and assuming sampling without replacement, that is, bolts drawn are not returned to the lot.
Neglecting losses, determine the power that can be developedfrom Niagara Falls, which has an average height of 168 ft and over which the water flows at 500,000 tons per minute.
Discuss how you can identify which resistances are in series and which ones are in parallel in a series-parallel circuit. How might this affect how you measure current and voltages in the circuit with a digital multimeter.
a circuit for an ac voltmeter utilizes a moving-coil meter that gives a full-scale reading when the average current flowing throught it is 1mA. The moving-coil meter has a 50-ohm resistance.
Draw the ROM truth table for the seven segment
Write an assembly program to calculate sum of number10 through 25
A 75 hp, 60 Hz, 2300 V, 20 A, 2 pole, wye connected, design B induction motor with code K delivers rated horsepower at 3500 r/min. Assume the phase angle of the locked-rotor impedance is 75 degrees.
