Question

A parallel-plate capacitor with circular plates and a capacitanceof 10.9 uF is connected to a battery which provides a voltage of12.0 V.

Part A: What is the charge on each plate? (In Coulombs)

Part B: How much charge would be on the plates if their separationwere doubled while the capacitor remained connected to the battery?(In Coulombs)

Part C: How much charge would be on the plates if the capacitorwere connected to the battery after the radius of each plate wasdoubled without changing their separation? (In Coulombs)
