Question
(a) When a 21.00-V battery is connected to the plates of a capacitor, it stores a charge of 30.0 µC. What is the value of the capacitance? Incorrect: Your answer is incorrect. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. µF (b) If the same capacitor is connected to a 15.00-V battery, what charge is stored? Incorrect: Your answer is incorrect. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. µC (a) When a 21.00-V battery is connected to the plates of a capacitor, it stores a charge of 30.0 µC.

The solution is as follows:
(a) By C = q/V
=>C = [30 x 10^-6]/21
=>C = 1.43 x 10^-6 F
=>C = 1.43 µF
(b) By q = CV
=>q = 1.43 x 10^-6 x 15 = 21.45 x 10^-6 C
=>q = 21.45 µC
