Multi LED and Resistor in Parallel: A Quick Guide

Learning how a parallel circuit works is the initial step in the study of electronics. A parallel circuit is one of the most popular circuits. It is helpful for students who are new to electronics to use the circuits to have some practical experience. The knowledge in this guide will give you a good foundation to work with it.

The aim of the parallel circuit is to illustrate how components can be circuited. Where several of light sources serve the purpose that each of them works independently. This circuit’s construction will enable you to learn the process of calculating the correct resistor values for LEDs, thus, ensuring their appropriate brightness and current levels.

In this circuit, you will use 5 LEDs, 5 resistors, a 9V battery, and jumper wires. Each LED must have a current-limiting resistor to avoid its burning out. To determine the values of the resistor for each LED, you can use Ohm’s Law.

Using a 220 ohm resistor should be safe as long as they are typical rated for around 20mA current. The current (9.1mA) with a 220 ohm resistor compared to the calculated 350 ohm resistor (5.7mA) will make the LEDs slightly brighter, but it should not damage them.

Figuring out this circuit is the best way to understand. How parallel circuits work and the basic principles of current flow and component interaction. It teaches to build circuits, solder, identify and solve problems through first-hand practice, which nowadays are crucial skills of any aspiring electronics lover. Through gaining a good understanding of this very simple circuit. Students can start working on more advanced circuits with ease, providing them for further studying electronics.
