Voltage divider rule:
The charge stored on a capacitor:
When the capacitor is fully charged, there is no current through R3. The voltage across the capacitor is equal to the voltage across R2.
VC = V2 = ε[R2/(R1 + R2)] = 42.0[6.00/(6.00 + 8.00)] = 18 V
The capacitor in the figure shown is initially uncharged. The switch is closed at t = 0.
What is the final charge on the capacitor?
