Homework Statement
A circuit is connected to charge a capacitor. The switch in the circuit is initially open, then closed at t = 0.
As t --> infinity, what is the voltage across the capacitor?
When does it reach 60 % of this limiting voltage?
Homework Equations
Not sure - maybe q = qf (1-e-t/RC)
The Attempt at a Solution
I think as t --> infinity, the voltage across the capacitor will be equal to the emf of the battery.
But I don't know what limiting voltage is, or how you find it. The only equation I could find involving time is the one above, but I'm not sure if or how that applies to this question.
