Series Resistors

Rtotal = R1 + R3

Parallel Resistors

Rtotal = R1 x R2/R1 + R2 (This is also known as product over sum)

Series Capacitors

Ctotal = C1 x C2/C1 + C2

Parallel Capacitors

Ctotal = C1 + C2

Rtotal = R1 + R3

Parallel Resistors

Rtotal = R1 x R2/R1 + R2 (This is also known as product over sum)

Series Capacitors

Ctotal = C1 x C2/C1 + C2

Parallel Capacitors

Ctotal = C1 + C2
