if there are two capacitors in series and the capacitance of one is known how would i find a value for the other?

The formula for finding the value of the second capacitor in a series with a known first capacitor is C2 = (C1*Ctotal)/(Ctotal - C1), where C1 is the value of the known first capacitor and Ctotal is the total capacitance of the series circuit.
The total capacitance in a series circuit can be calculated by adding the reciprocal values of each individual capacitor and then taking the reciprocal of the sum. So for a series circuit with capacitors C1 and C2, the total capacitance would be 1/Ctotal = 1/C1 + 1/C2.
No, this formula is specifically for finding the value of the second capacitor in a series circuit. For capacitors in parallel, the total capacitance can be calculated by simply adding all of the individual capacitance values together.
The units used for capacitance should be farads (F) or its subunits such as microfarads (μF) or picofarads (pF). Make sure to convert any other units into farads before plugging them into the formula.
This formula assumes ideal conditions and does not take into account factors such as internal resistance or the frequency of the circuit. It is best used for basic calculations and may not be accurate for more complex circuits.
