A 120/240V single phase transformer is connected as an autotransformer. Suppose that V1 is 120V at zero degrees and the transformer is ideal. Find V2, I1, and I2.
(1) What might be an example of an input and an output What are some simple examples of what constitutes the distinction between input into a program and output from the program (2) What type of arithmetic operations are supported in C++
Sketch the Capacitance-Voltage characteristics for both devices based on part (d) by giving appropriate labeling to the voltage and capacitance axis. You may assume high f measurements.
Given the following function in product-of-sums form, not necessarily minimized, F(W,X,Y,Z) = (W + X' + Y')(W' + Z')(W + Y), Re-express the function in the canonical sum-of-products form. Use little m notation.
calculate the losses in the transformer under these conditions. losses and efficiency when the transformer delivers its rated power to a load having a power factor of 90%
i) Calculate the number of calls/hour/cell and the number of calls/hours/km2 ii) Calculate the number of users/hour/cell and the number of users/hours/channel iii) Find the modulation frequency for this system.
Design a series controller (a PD, PI or PID) so that the following performance specifications are satisfied. Steady-state error due to a step input = 0
Design a current divider that will provide a 1/3-2/3 current splitting ratio. Use resistance in kilo ohm range. Redesign the current divider so that the resistors are less than 100 ohms but maintain the same 1/3-2/3 splitting ratio.
Two resistances R1 and R2 are connected in series. We know that R1=60 ohms and that the voltage across R2 is three times the value of the voltage across R1. Determine the value of R2.
3) If the input voltage to a Full-Wave Bridge Peak Rectifier is vi(t) = 10.4sin(600t) Volts, what is the peak output voltage. Assume all diodes have a 0.7V drop, (ie. VD = 0.7V). 4) For the previous problem, if the resistor in the circuit is equal t..
