# Parallel Circuit Rules

#### Chapter 1 - Useful Equations And Conversion Factors

- Components in a parallel circuit share the same voltage. E
_{total}= E_{1}= E_{2}= . . . E_{n} - Total resistance in a parallel circuit is
*less*than any of the individual resistances. R_{total}= 1 / (1/R_{1}+ 1/R_{2}+ . . . 1/R_{n}) - Total current in a parallel circuit is equal to the sum of the individual branch currents. I
_{total}= I_{1}+ I_{2}+ . . . I_{n}
