Concept

Problem: You need a capacitance of 50 μF, but you don't happen to have a 50 μF capacitor. You do have a 30 μF capacitor. A. What additional capacitor do you need to produce a total capacitance of 50 μF B. Should you join the two capacitors in parallel or in series?

FREE Expert Solution

For 2capacitors in series, the equivalent capacitance is:

Ceq=C1C2C1+C2

For capacitors in parallel, the equivalent capacitance is:

Ceq=C1+C2+...+Cn

If we have a 30μF capacitor and need a 50μF capacitor, we can consider any connection we want.
