A ideal transformer is rated at 4800/480 volt, at 75KVA. it is connected as a step down auto transformer. find the line and load voltages, turns ratio and total apparent, real and reactive power at full load and at 60% rated load at a power factor of .9 lagging
The command in AutoCAD can be a time-saver, particularly when you're working in an application where you want to move a door or windows within walls on a drawing and don't want to redraw the walls.
A digital signaling system is required to operate at 9600 bps. If a signaling element encodes a 8-bit word, what is the minimum required bandwidth of the channel?
Consider a coffee counter with a single server at which tired students arrive according to a Poisson process. Let the mean arrival rate be two students per ten minutes and assume the serving time is exponentially distributed with an average of 180..
An OpAMP has a unity gain frequency (ft) of 10MHz and a slew rate of 10V/us and AVoc = 120dB at DC (f=0). Assume VCC = -VEE = 15 Volts.a. Approximate the cutoff frequency of the OPAMP itself. b.
Bode plots were introduced in my second circuit analysis class, but I really didn't think it was important because it looked like an outdated tool no longer in use.
A 240kW 500V 1750 r/min separately excited dc generator has an overall efiiciency of 94%. The shunt field resistance is 60 ohms and the rated current is 5A. The I^2 R loss in the armature is 0.023 pu.
Hand calculate the expression for the voltage and current of the capacitor and plot these equations by using MATLAB and calculate the time constants of each circuit and point out this time constants at your voltage graphs.
