11.14 QUESTIONS
- What is the differential equation describing vc(t) for t ≥ 0+ in the circuit in Fig. 11.14-1?
- A parallel RC circuit with non-zero initial energy is driven by u(t) A. vC(t) is found to reach 75% of its steady-state value in one time constant. Express the initial voltage across the capacitor as a percentage of its steady-state value.
- A parallel RC circuit is driven by u(t) A. vC(t) is found to be 50% at t = τ. Was there any initial voltage across C? If yes, what is its magnitude and polarity?
- Find and plot the vC(t) and voltage across the current source as functions of time in Fig. 11.14-2. Is there any exponential function ...
