1 For the circuit given in Fig. 18-14, the R C2, fc are given find the switched capacitor equivalent

sequence. The balanced source supplies IMW and 0.2M VAR. If R, =12, find: (a) the line current;(b)Zp; ()the transmission efficiency

1. In the circuit shown in the Fig 3-15, it is desired that 23 2v, a)Find the value of R that gives the desired relationship. b) Suppose that v,=-10V and v2=10V, find the magnitude of the currents through all resistors and the powers dissipated by all resistors

Example 2: (p175-12) resistor, capacitor, and voltage source=100cos300n are all in series. If the average power dissipated by the resistor is 150W and the rms capacitor voltage is 10v, determine R and C
