(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The capacitor in an RC circuit (R = 130 \Omega, C = 40uF) is initially uncharged.

1) Find the charge on the capacitor in the circuit one time constant (tau = RC) after the circuit is connected to a 9.0- V battery.

2) Find the current in the circuit one time constant (\tau = RC) after the circuit is connected to a 9.0-V battery.

2. Relevant equations

R = V/I

Q = qo[1-e^-t(RC)] ???

3. The attempt at a solution

Im actually not sure I even have the correct equations and I'm not sure what to use for qo
