I missed this day in class and was wondering if any one could guide me in the right direction. 24) Assume you need total cap of 2.1 microF but all you got are a .22 microF .47 microF cap`s ... DC

Do you know how to calculate resistance of series and parallel circuits? Capacitors are just the opposite. Capacitors in parallel add, capacitors in series are the reciprocal of the sum of the individual reciprocals (like parallel resistors)

The capacitance is worked out as the opposite way to resistance. Series resistance is the same method for parallel capacitance.

Rt = R1 + R2 (in series) is same as Ct = C1 + C2 (in parallel)

1/Rt = 1/R1 + 1/R2 (in parallel) is same as 1/Ct = 1/C1 + 1/C2 (in series)

After reading some of your posts, I see that you seem to be easily amused. Can you tell us what you found to be so humorous?
