AoE Exercise 1.17

00:19:28

Use Thévenine equivalent of the voltage divider formed by R1 and R2, you can find the output V(t) produced by a step input for Vin.

R1=R2=10K
C=0.1uF
Vin=step input (no voltage level and period given, so I set the period to 5ms, to look good)

On the left: original circuit

On the right: Thévenine equivalent of the voltage source and the divider

Vth=Vin/2
Rth=5K

RC=5K*0.1uF=0.5ms
5RC=2.5ms (approx. total charge/discharge time of the capacitor)
