Question

How do you add capacitances for two capacitors, C_1 and C_2, when connected in parallel? 1/C_1 = 1/C_1 + 1/C_2 C_1 = C_1 + 1/C_2 C_1 = 1/(C_1 + 1/C_2) 1/C_1 = C_1 + C_2 C_1 = C_2 C_1 = 1/C_1 + C_2 C_1 = (C_1 + C_2)^2 C_1 = 1/C_1 - 1/C_2 Suppose after charging a 5.7 mu F capacitor to 6 V, you connect it to the second uncharged capacitor of 14.9 mu F What voltage will your voltmeter read across the second capacitor after repeating the charge sharing process two times? Express the answer with one decimal place.

Explanation / Answer

Question 1 :

for Capacitances in Parallel , combination of Capacitances is the sum of all the Capacitances in parallel

hence Ct = C1 + C2
