Answer to Question #322403 in Physics for Cring

Question #322403

An RC circuit have a 9 V source and lies at a 54-seconds of time constant.

Then, find the voltage across the Capacitor after 153.6 seconds of charging.

Expert's answer

"V_C(t)=V_s\\left(1-e^{-t\/\\tau}\\right)"

"V_C(t)=9\\:{\\rm V}\\left(1-e^{-153.6\/54}\\right)=8.48\\:\\rm V"
