Unit 6 Series Circuits
Rules for Calculating Series Circuit Values
1. The current is the same at any point in the circuit.2. The total resistance is the sum of the individual
resistors.3. The applied voltage is equal to the sum of the
voltage drops across all the resistors.

Unit 6 Series Circuits
Formulas for Calculating Series Circuit Values:
ITOTAL = I1 = I2 = I3 ……= INUMBER OF RESISTORS
RTOTAL = R1 + R2 + R3 ..…+ RNUMBER OF RESISTORS
ETOTAL = E1 + E2 + E3 …..+ ENUMBER OF RESISTORS

Unit 6 Series Circuits
Example of Series Circuit Values
ITOTAL = I1 = I2 = I3 = 2 A
RTOTAL = 20 Ω + 10 Ω + 30 Ω = 60 Ω
ETOTAL = 40 V + 20 V + 60 V = 120 V

Unit 6 Series Circuits Power in a Series Circuit
The total power used in a circuit is equal to the sum of the power used by all parts.
PTOTAL = P1 + P2 + P3 …… PNUMBER OF RESISTORS
