1. The problem statement, all variables and given/known data A 10V supple is connected to a 2.2μF capacitor in series with a 10kΩ resistor. To what value will it have charged after three time constants? 2. Relevant equations I know that T=RC but I have no idea beyond this point 3. The attempt at a solution T=RC T=2.2μF*10kΩ T=22 the rest is unknown to me, if someone could explain it to me that would be awesome.
