A 10 F, 20 F, 22 F, and 100 F capacitor are in parallel. What is the total capacitance?
The answer is:
- The difference of potential (
#DeltaV#) across the two capacitors is the same (the one of the generator);
- Q is divided between the capacitors;
#C_1 and C_2 and C_3 and...#are different, so #Q_1 and Q_2 and Q_3 and...#are different.
To find the equivalent capacitor of two or more capacitors in parallel it is necessary to use this formula:
In this case:
