Series Circuit Rules

Current

Components in a series circuit share the same current:

• I_total = I₁ = I₂ = . . . I_n

Resistance

Total resistance in a series circuit is equal to the sum of the individual resistances, making it greater than any of the individual resistances:

• R_total = R₁ + R₂ + . . . R_n

Voltage

Total voltage in a series circuit is equal to the sum of the individual voltage drops:

• V_total = V₁ + V₂ + . . . V_n
