A bank of induction motors cosumes 36kW at 0.78pf lagging from a 60 Hz 240V RMS line. If 200μF of capacitors are placed in parallel with the load, what is the new power factor of the total load
Derive the state space quation of a DC motor with supply voltage and load torque as inputs and armature current, angular speed as outputs.
Explain the structure and nature of the ionosphere with reference to daily, seasonal and long-term changes and explain the modes of propagation of radio waves of different frequencies
An isotropic antenna is radiating a total power of P0W. A receive antenna is located 2km from the radiator. It has a gain described by the equation with loss factor and an effective aperture of Aer1=600cm2 .
Unfortunately, nick is pretty lazy and doesn't want to design another filter. thinking twice the filtering gives twice the proforamce," he suggests filtering the audio signal not once or twice with a cascade of 2 idential filters.
An OpAMP has a GBWP of 100MHz and a slew rate of 10V/us and AVoc = 160dB at DC. Assume VCC = +/- 15 Volts. a. If the opamp is configured as a non inverting amplifier with voltage gain of 50.
