## Parallel Resistors Calculator

Published on

A parallel circuit can be identified by the presence of a consistent potential difference (voltage) across the ends of all of the resistors.

When resistors are connected in parallel, the equivalent resistor has a value that is lower than the resistor that has the lowest value among the resistors that are connected in parallel. Because adding a new resistor in parallel creates a new path for current to follow, the total current after adding the new resistor is higher than the value it was before adding the new resistor; consequently, the total resistance is always lower than the resistance it had been before adding the new resistor.

# Formula:

where:

RT = equivalent parallel resistance

R1, R2 = resistances of individual resistors
