Two-wattmeter method is used to measure the power taken by a 3-phase induction motor on no load. The wattmeter readings are 375w and -50w.
Calculate;i)power factor of the motor at no load
ii)phase difference of voltage and current in two wattmeters.
a) How long does it take for the soprano's voice to reach the listener b)In the same time interval, how far form the soprano has the sound wave in the auditorium traveled. Take the speed of sound to be 340 m/s.
To ensure a reproducible thermal contact resistance between the chuck and the wafer from cycle-to-cycle pressurized helium gas is introduced at the center of the chuck and flows (very slowly) radially outward between the asperities of the interfac..
A 1000.0 kg car is moving at 15 km/h. If a 2000.0 kg truck has 18 times the kinetic energy of the car, how fast is the truck moving in km/h
Experts claim that the water supply system in the U.S. is the safest and most drinkable in the world. Write a research report on factors that have adversely influenced water quality in other parts of the world.
Your circuit should output a signal X that can be used to turn a buzzeron or off, where high implies on. The buzzer should be on if theignition is on and if the door is open or the seat belt is notfastened. Draw your logic circuit and construct a ..
Design a multistage op ampbased amplifier that has a gain of -900 V/V and a bandwidth of atleast 120 kHz. You have Op Amps with unity gainbandwidths of 2 MHz and 3 MHz. Each has a slewrate of 6 V/ms.
determine the transfer function of a 4th order lowpass butterworth filter with a 3-dB cutoff frequency of 3.4 kHz and passband gain=1. Design the circuit using MFB topology. Design two sections with an order of 2.
Given the characteristic equation: F(z) = z^3 + z^2 + kz - 0.5 = 0 a) Use the Jury test to determine the range of "k" that ensures the system is BIBO stable. Show any inequality graphs and how they are combined to determine the valid range of k.
Design a proportional-integral (PI) controller (recommend to use matlab siso toolbox) so that phase margin of the loop transfer function should be over 35o, and the crossover frequency is no larger than 10kHz - Analytically determine and draw t..
