1 The switch in Fig.5-27 is opened at=0, Find i (0*) and v (0*) 1kΩ D100v 1k2 Fig. 5-27 For prob.1. The switch is closed at= 0 in Fig.5-28. Find i(*) and ic(0*) if the capacitor is initially
We define the unit impulse as a function of time which is zero when its argument, generally (t-o), is less than zero; which is also zero when argument is greater than zero; which is infinite when its argument is zero; and which has unit area
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
The forced response The steady state responseThe(t) has been switched into the circuit at some remote U.=V. cos ot time in the past, and the natural response has died-out completely. The forced response(steady state response)must satisfy the differential equation
