• Components in a parallel circuit share the same voltage:
• Etotal = E1 = E2 = . . . En
• Total resistance in a parallel circuit is less than any of the individual resistances:
• Rtotal = 1 / (1/R1 + 1/R2 + . . . 1/Rn)
• Total current in a parallel circuit is equal to the sum of the individual branch currents:
• Itotal = I1 + I2 + . . . In
