11.15 PROBLEMS
(Initial condition values are zero unless specified otherwise.)
- The switches in Fig. 11.15-1 are ideal. (i) Find the voltage across C and plot it. (ii) Find the current through C and plot it. (iii) Find the voltage across the first resistor and plot it.
- Initial voltage at t = –∞ in the capacitor in the circuit in Fig. 11.15-2 was zero. Find the voltage across capacitor and current through it for t ≥ 0+ and plot them.
- The switch in the circuit in Fig. 11.15-3 was closed for a long time and is opened at t = 0. Find and ...
