Series circuit rules

• Components in a series circuit share the same current. I_total = I₁ = I₂ = . . . I_n
• 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
• Total voltage in a series circuit is equal to the sum of the individual voltage drops. E_total = E₁ + E₂ + . . . E_n
