Question

Can you check if my answers are correct

(a) Determine the time constant of the circuit.

= 5.6ms


(b) Write the mathematical equation for the voltage vC following the closing
of the switch.

Vc = 25(1 - e-t/5.6ms)V

(c) Write the mathematical expression for the current iC following the closing of the switch.

This one was tricky since I guess that 25V is considered E voltage. so I thought this would be divided by the resistor which I got Ic = 0.446e-t/5.6ms


(d) Sketch the waveforms of vC and iC
