What is the formula for solving capacitance in a series and parallel circuit?
Series: Ct= 1/(1/C1 + 1/C2 + 1/Cn) OR Ct= (C1 x C2)/(C1 + C2)

Parallel: Ct= C1+C2+Cn
When solving capacitors it is the opposite of what other component?
Resistors
The total for inductance in a parallel and series circuit is the same as what component?
Resistors
What is the formula for inductance in parallel and series?
Series: Lt= L1+L2+Ln

Parallel: 1/Lt= 1/L1+1/L2+1/Ln OR Lt= 1/ (1/L1+1/L2+1/Ln) OR Lt= (L1xL2)/(L1+L2)
