A capacitor in an RC circuit is charged to 68.0% of its maximum value in 0.980 s. What is the time constant of the circuit?(adsbygoogle = window.adsbygoogle || []).push({});

>> I know the time constant is equal to Q/(Q/t) and that t = 0.980 s. I also know that Q = CE and E is a constant. But they don't tell me the capacitance to use... Bah I'm really stuck and confused :( Does anyone know how to solve this?
