The 2-microfarad (2 × 10^–6 farad) capacitor shown in the circuit above is fully charged …
a. b. When the switch is closed, there is no charge on the 6 μF capacitor so the potential difference across the resistor equals that across the 2 μF capacitor, or 2000 V and I = V/R = 2 × 10-3 A c. In equilibrium, charge is no longer moving so there is no potential difference across the resistor therefore the capacitors have the same potential …

Capacitors when charged are equivalent to a DC voltage source, and the circuit components connected across the capacitor''s terminals determine the magnitude of the discharge current. Any such current reduces the amount of charge, and therefore also reduces the voltage across the terminals of the capacitor.
