Rules for Parallel Circuit

  • If there is an open part of the circuit, current will flow in the remaining parallel paths.
  • Each part of a parallel circuit has the same voltage.
  • The total current of a parallel circuit is the sum of each individual current between components.
  • Total Resistance is calculated using the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3…​ This means that the total resistance of a circuit gets smaller with each resistor.

What does all this mean? Well, lets take a circuit and calculate some numbers
