Capacitance in Parallel Circuits
Capacitance in a parallel circuit is additive.
This is a short hand way of saying that the total capacitance in a series
circuit equals the sum of each of the capacitance values in the circuit.
So the formula is Ct = C1 + 2C + C3 + C4 in a circuit with 4 components.
If you know the total capacitance and all individual capacitance values
except one, then the capacitance of the missing value can be calculated by
subtracting all known individual capacitance values from total capacitance. The
result will be the capacitance of the individual missing component.
Here are formulas for a circuit with 4 components when one is missing and
you know the total:
If C1 is missing, then C1 = Ct - C2 - C3 - C4
If C2 is missing, then C2 = Ct - C1 - C3 - C4
If C3 is missing, then C3 = Ct - C1 - C2 - C4
If L4 is missing, then C4 = Ct - C1 - C2 - C3
