Series circuit rules
- Components in a series circuit share the same current.
Itotal = I1 = I2 = . . . In
- Total resistance in a series circuit is equal to the sum of the individual resistances, making it greater than any of the individual resistances.
Rtotal = R1 + R2 +. . . Rn
- Total voltage in a series circuit is equal to the sum of the individual voltage drops.
Etotal = E1 + E2 + . . . En
