5. In Figure 33, replace the alternating-current element with a direct-current element E 50 volts and use R = 10 ohms, C = 4(10) farad. Assume that when the switch is closed (at t = 0) the charge on the capacitor is 0.015 coulomb. Find the initial current in the circuit and the current for t > 0. Ans. 1(0) = 1.25(amp), I(t) = 1.25 exp (-250t) (amp). %3D %3D R E sin wt FIGURE 33
