Motor and Motor Control Circuits Course Project 1 Quiz Answers ....Refer to our video lab on specifying a DC motor speed measurement. How does an FET work? Comment your answer below .... Refer to our video lab on specifying a DC motor speed measurement. How do you measure back EMF directly? It is not possible to measure the back EMF directly ....Refer to our video lab on specifying a DC motor speed measurement. Sup. pose the motor resistance is 2 ohms, motor inductance is 5 milli-henries, external voltage is 5 volts, and the back EMF time constant is .009 per RPM. As the motor accelerates, what is the motor current in milliamps at time t = 20 milliseconds when the motor is running at 500 RPM. Ignore any oscillation of the back EMF voltage due to commutation. Type an integer value of milli-amps. 250 ....Refer to our video lab on specifying a DC motor speed measurement. Why does the frequency of ripples in the de caying DC current signal increase as the motor speeds up? Select all that a...
