Question

The hospital you work for uses a defibrillator that has a single capacitor with a capacitance of 10^-6 F. When it is about to be used, the defibrillator is charged to a voltage of 4000 V.
a) How much charge is stored on the defibrillator ‘s capacitor when it has been fully charged?

b) If you were to connect an additional 3 x 10-6 F capacitor in parallel with the original 10-6 F capacitor in the defibrillator, what would be the equivalent capacitance?

c) Increasing the separation between the capacitor plates while hooked up to the voltage source will decrease the charge stored for what reasons?

d) How much energy is stored in the defibrillator ‘s capacitor (10-6 F) when it has been fully charged across 4000V?
