Which capacitor is connected to a battery if the plate areas are equal?

Here as the plate areas are equal, A parallel plate capacitor of capacitance C is connected to a battery and is charged to a potential difference V. Another capacitor of capacitance 2C is connected to another battery and is charged to potential difference 2V.

Which is the required equivalent capacitance?

Share the knowledge! Which clearly shows that capacitance does not depend on charge on both the conducting plates. Hence answer is This is the required equivalent capacitance. A parallel plate air capacitor with no dielectric between the plates is connected to the constant voltage source.

What if a capacitor has the same potential difference?

If the capacitor that is equivalent to the combination has the same potential difference, then the charge on the equivalent capacitor is the same as: If 4μF and 2μF capacitors are conneced in series, the equivalent capacitor is ___________. Already have an account?
