What Is The Equivalent Resistance In A Parallel Circuit

By | July 19, 2022



No matter what kind of electrical circuit you are dealing with, understanding the principles of resistance is essential for electricians. When it comes to understanding resistance in a parallel circuit, the basic concepts remain the same but the math becomes slightly more complicated.

A parallel circuit is one with multiple paths along which electricity can flow. This differs from a series circuit, where electricity must travel along one route to reach each junction. As such, the resistance in a parallel circuit is calculated differently than that in a series circuit.

In a parallel circuit, the total resistance is calculated by adding up the values of all the resistors. To determine the equivalent resistance, however, we must use Ohm’s law, which states that voltage is equal to the current multiplied by the resistance.

The first step in calculating the equivalent resistance of a parallel circuit is to calculate the individual resistances. This is done by dividing the voltage applied across the two paths by the current draw on each path. The individual resistances can then be added together to calculate the total resistance.

Next, to calculate the equivalent resistance, we must divide the total resistance by the number of resistances in the circuit. This gives us the value of the equivalent resistance. For example, if there are three resistors in the circuit with individual resistances of 3 ohms, 4 ohms, and 6 ohms, then the total resistance is 13 ohms, and the equivalent resistance is 4.33 ohms (13/3).

Understanding the equivalent resistance in a parallel circuit is not only important for electrical engineers but also for anyone who wants to have an understanding of electricity. By getting to grips with the basics of parallel circuit resistance, you will have a much better understanding of any electrical system you are working with.

From calculating the individual resistances to finding out the equivalent resistance, these are vital calculations for anyone dealing with electricity. With a better understanding of resistance, you’ll be able to tackle more complex circuits and reap the benefits of a successful electrical project.
