If a constant voltage drop of 16 V is maintained across an inductance of 140 mH that was initially carrying 1.6 A of current, how much time elapses before the inductor's stored energy reaches 590 mJ?
A 74.6-kW, three phase, 440-V (line to line), four pole, 60-Hz induction motor has the following (per phase) parameters referred to the stator circuit: Rs=0.06-Ω, Rr=0.08-Ω, Xs=0.3-Ω, Xr=0.3-Ω, Xm=5-Ω The no-load power input is 3240-W at a current ..
What is the common-mode rejection ratio (in dB) if the output voltage is measured to be 2.0 Vp-p when the input terminals are connected together and a 0.1 Vp-p voltage is applied between the inputs and ground.
A given low pass filter has a cutoff frequency fc and a sample frequency fs. The sampling period is T = 1/fs. In implementing the filter it is essential that the evaluation of the difference equation be completed in less.
What is the difference between the saturation and active regions of a BJT. What determines which region the transistor is in.
Assume the factory described in the previous problem is fed from a line having an impedance of 0.02 + j0.16-ohm. The voltage at the factory is maintained at 480 V(rms). Find the average power loss in the line before and after the load is added.
build a circuit for a parking deck where a binary counter counts up when a car comes in and down when one leaves. There can only be a maximum of 40 cars in the parking deck before an LED turns on to notify the parking deck is full.
You have a 120 VAC motor pump system. The system will work in a voltage range from 100 to 130 volts. you can count on the minimum voltage from the supplier to be 115 VAC. The wiring will consist of #14 awg which has a resistance of 2.5 ohms/1000 f..
