Question

You are charging a capacitor with capacitance C through a resistance R, using a battery of emf E, starting at t=0. Sketch the circuit, and a plot of the charge on the capacitor vs. time, q(t). Write down the value q will approach after a long time. Long compared to what?

Hello. Please help me with this question. I don't need to the plot which I got it. I am kind of confused about the definition of value q. Please just answer "Write down the value q will approach after a long time. Long compared to what?". Thank you guys.

Explanation / Answer

Q=Qo(1-e^-(t/RC))

t>>RC

long compared to time constant RC

at t>>RC
Q=Qo
