Read the RC-transient class notes.


For the circuit shown,

  • R = 150 Ω
  • C = 10 nF

For the RC circuit, the source voltage has been at an initial voltage of Vi = 3 V for a long time. At t = 0, the source voltage abruptly jumps to Vf = 21 V.

Determine the expression for the capacitor voltage as a function of time, for t > 0.

Calculate the time when the capacitor voltage will be equal to 6 V and calculate the capacitor current at that time.
