The circuit of Figure is a two-stage, first order cascade circuit that will be studied extensively in Chapter 14. It is a second-order circuit whose zero-state, step response can be solved by recognizing that since R and C are the same, the solution fits Case B for the natural response v2N(t) (Eq. (7-65b)).
(a) Find the output v2(t) when the input vS(t) = 5u (t), R = 10 kΩ, and C = 0.1 μF.
(b) Use MATLAB to plot your result.
(c) Simulate the circuit using Multisim and compare your results.
The current through a 2-μF capacitor is shown in Figure. At t = 0, the voltage is zero. Sketch the voltage, power, and stored energy to scale versus time.
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..
The power factor of the added load is to be adjusted so that the overall power factor of the factory is 0.96 lagging. The factory is fed from a line having an impedance of 0.02 + j0.16 O. The voltage at the factory is maintained at 480 V(rms).
