Question

A 21 mu F and 15 mu F capacitor are connected in parallel to a 12V battery. What is the charge on the 21 mu F capacitor? Enter your answer in mu C. A 1 mu F and 11 mu F capacitor are connected in series to a 12V battery. What is the charge on the 1 capacitor? Enter your value in mu C. A 3 mu F capacitor and an 18 mu F capacitor are connected in series to a 12V battery. What is the voltage on the 3 mu F capacitor? A 12V battery is connected to a capacitor, resulting in 19 mu C of charge on the capacitor. How much energy is stored in the capacitor?

Explanation / Answer

Question 5

charge of 21 uf =21*12=252 uC

Question 6

charge =net capactance*voltage

net capacitance=(1*11)/12=11/12 uF

chagre=11 uC

Question7

voltage on 3 uF=18/(18+3) *12=10.29 V

Question 8

Energy=0.5*Q^2/C=1.14*10^(-4) J
