Parallel Resistance calculation in Android application

Updated: Nov 18, 2020

Resistors are in parallel when their two terminals connect to the same nodes.

Resistors are often connected in series or in parallel for creating more complex networks. The voltage across resistors in parallel will be the same for each resistor. But, the current will be in proportion to the resistance of each individual resistor.

The purpose of finding the equivalence resistance is that we can replace any number of resistors connected in a parallel combination by the equivalent resistance of the parallel combination resistors.

If two or more resistors are connected in parallel, then the potential difference across all the resistors is the same. Resistors in parallel connection are connected to the same nodes from both ends.

This can be identified by the presence of more than one way for the current to flow. The potential difference across the resistors is the same as that across the resistor which is equal to the supply potential.

Resistors in Parallel:

case 1.

Consider the following circuit where four resistors R1, R2, R3 and R4 are connected in parallel:
