Question

5. The initial voltage across the capacitor is 0 V. At time t=0, the switch is closed a) What is the time constant t for this circuit?After the switch has been closed: b) What is the maximum instantaneous current that will flow through the capacitor? c) What is the final voltage V-(∞) across the 40µFcapacitor? d) When will the voltage V, reach 5.0 V? e) Sketch the waveform for V.(t).
