In the circuit of Fig 27-57 epsi=1.2kV, c=6.5muF, R_(1)=R_(2)=R_(3)=0.73 M Omega. With C completely uncharged switch S is suddenly closed (at t=0). At t=0, what are (a) current i_(1) in resistor 1, (b) current i_(2) in resistor 2, and (c) current i_(3) in resistor 3? At t=oo (thta is after many time constants). what are (d) i_(1), (e) i_(2) and (f) i_(3)? What is the potential difference V_(2) across resistor 2 at (g) t=0 and (h) t=oo? Sketch V_(2) versus t between these two extreme times. |
