# Parallel Resistors Equivalent Resistance Calculator

**Parallel Resistors Calculator** is an online tool for electrical and electronic circuits to measure total resistance of the resistors which are connected in parallel. Resistor is the material resist the flow of current to some extent. The electrical resistivity always expressed in Ohms and the power dissipation occurs on the resistor is called as resistance of the material. The resistance R of a given material is directly proportional to its length L and inversely proportional to its area of cross section A. In electrical and electronics circuits, the resistivity of the resistors can be calculated by adding every reciprocal value of individual resistance. When it comes to online calculation, this Parallel Resistor Calculator can assist you to find out the total resistance value based on the input values of R_{1} and R_{2}. The parallel connection of resistors total resistance can be mathematically derived from the following equation
