In a series circuit, the Total Circuit Resistance(Rt) is equal to the sum of the individual resistances. As an equation, it can be written as follows:
Rt = R1 x R2 x R3...Rn
Rt = R1 + R2 +R3...Rn
Rt = Vt ÷ It
Rt= Rn(R1 + R2 + R3)

The total Power consumption (PT) of series circuit is equal to the sum of the individual power consumptions.
PT = P1 + P2 + P3 + ... PN
PT = P1 - P2 - P3 - ... PN
PT = P1 x P2 x P3 x ... PN
PT = P1 + P2 - P3 x ... PN
