What Is The Effective Resistance In A Parallel Circuit

By | September 4, 2022



We often think of electricity as something mysterious and intangible, but understanding how electric current works is actually much simpler than you might think. When it comes to electric circuits, two of the most important concepts to understand are resistance and parallel circuits. In a parallel circuit, the effective resistance is equal to the sum of each individual resistor’s resistance in the circuit.

The term "resistance" refers to how difficult it is for electric current to flow through a material. All materials have electrical resistance and some materials, such as copper and silver, have very low resistance while other materials, such as rubber, have very high resistance. Whenever electric current passes through a material or a wire, some of the energy is lost in the form of heat due to the resistance of the material.

In a parallel circuit, electric current is split into multiple paths. This means that the total resistance is reduced, since each path has less resistance than the single path of a series circuit. The formula for calculating the effective resistance of a parallel circuit is simply the sum of each individual resistor’s resistance divided by the number of resistors.

For example, let’s say we have a circuit with three resistors. Each resistor has a resistance of 5 ohms. The effective resistance of the parallel circuit would be calculated as 5/3=1.67 ohms. This means that the total resistance of the circuit is 1.67 ohms.

It’s important to note that the effective resistance of a parallel circuit is always lower than the resistance of any single resistor. This is due to the fact that the combination of multiple resistors reduces the overall resistance. This principle can be used to effectively reduce the resistance of a circuit, allowing for more current to flow through.

Understanding the principles of parallel circuit resistance can provide important insights into how electric current works. With a basic understanding of how resistance works in a parallel circuit, engineers and electricians can begin to design intricate electrical systems for a variety of applications.
