第3节 Parallel Circuit Rules (修订中)

[TOC]

# 1. Voltage

Components in a parallel circuit share the same voltage:

  • Etotal = E1 = E2 = . . . En

# 2. Resistance

Total resistance in a parallel circuit is less than any of the individual resistances:

  • Rtotal = 1 / (1/R1 + 1/R2 + . . . 1/Rn)

# 3. Current

Total current in a parallel circuit is equal to the sum of the individual branch currents:

  • Itotal = I1 + I2 + . . . In
