The
total resistance of a set of
resistors in parallel is found by adding up the reciprocals of the
resistance values, and then taking the reciprocal of the
total: equivalent
resistance of
resistors in parallel: 1 / R = 1 / R
1 + 1 / R
2 + 1 / R
3 +... A
parallel circuit is shown in the diagram above.

Resistors in parallel
In a parallel circuit, the net resistance decreases as more components are added, because there are more paths for the current to pass through. The two resistors have the same potential difference across them. ... The total current in the circuit is the sum of the currents through each branch.
