the circuit is developed between the left plate of C1 and the
right plate of C2. Because these plates are farther apart, the
total value of the capacitance in the circuit is decreased.

For example, the value of three (3) 0.015 microfarad capacitors
connected in series is 0.005 microfarads. If the circuit
contains more than two capacitors, use the formula above. If
the circuit contains only two capacitors, use the formula below:
C1 x C2
CT =
C1 + C2
