# Charge on a Capacitor in an RC Circuit

EANDM-BJQ@GW

In the RC circuit below the capacitor is initially uncharged. At time $t = 0 \:\text s$ the switch is closed and the capacitor begins to charge. The circuit parameters are: $\Delta V = 10.0 \:\text V$, $R = 1.00 \:\text k \Omega$, $C= 20.0 \: \mu \text F$.

What is the charge on the capacitor at $t = 25.0 \:\text {ms}$?

A

$1.42 \:\mu \text {C}$

B

$250 \:\mu \text {C}$

C

$1.99 \:\mu \text {C}$

D

$7.13 \:\mu \text {C}$

E

$0.04 \:\mu \text {C}$
