When more than two resistors are connected in parallel the equation becomes:
The following resistor network is set up.
Calculate the total resistance of the network.
This means that the three individual resistors can be replaced by one resistor of .
Adding resistors in parallel decreases the total resistance.
The current has a choice of paths and only has to pass along one branch of the circuit.
It does not pass through each resistor and the total resistance of a parallel circuit is always smaller than the smallest resistor.
