Question:

Your company is still stuck with those 2μF capacitors from Problem 44. They turn out to be so cheap that their capacitances are all too low, ranging from 1.7 μF to 1.9 μF. A colleague suggests you put variable “trimmer” capacitors in parallel with the cheap capacitors and adjust the combination to precisely 2.00 μF. The available trimmers have variable capacitance from 25 nF to 350 nF. Will they work?

Data From Problem 44

Your company’s purchasing department bought lots of cheap 2.0μF, 50-V capacitors. Your budget is maxed out and they won’t let you buy additional capacitors for a circuit you’re designing. You need 2.0μF, 100-V capacitors and 0.5μF, 50-V capacitors. How will you combine the available capacitors to make these?
