Document Summary

[1] the switch in fig. has been in position (a) until t = 4 s then it is moved to position (b) and left there. [2] for the circuit shown, the switch is closed at t=0 when the initial capacitor voltage =20 v. [3] for the circuit shown, the switch has been. 6 closed for a long time then opened at t = 0. Find : v(t) for t 0, the energy stored at the capacitor at t=0. 24 v (w(0)): the current in the 12 resistor . [4] the switch in the circuit in fig. has been closed for a long time. The switch is opened at t = 0. [5] for the shown circuit, the switch is closed for a long time then opened at t=0. Determine i, io, and vo for at t >0. [6] for the shown circuit, the switch is closed for a long time then opened at t=0.
