Current

Components in a series circuit share the same current:

  • Itotal = I1 = I2 = . . . In

 

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:

  • Rtotal = R1 + R2 + . . . Rn

 

Voltage

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

  • Etotal = E1 + E2 + . . . En
