How To Read A Resistor On Pcbs Globalwellpcba With practice, reading these codes becomes second nature. once you know how to decode resistors, you can confidently work on any pcb! step by step guide: how to read a resistor on a pcb. reading resistors on a pcb can be tricky if you're new to it. but don't worry—this guide will help you through each step. A pcb (printed circuit board) is the backbone of almost every electronic device. it's the flat, usually green, board you see inside gadgets. the pcb connects and holds all the electronic components in place. at its core, a pcb is made up of several layers. the most important one is the copper layer.
How To Read A Resistor On Pcbs Globalwellpcba Plug in the probes: the red probe goes into the multimeter's positive terminal, and the black probe goes into the negative terminal. select the function: decide what you need to test—voltage, resistance, or continuity. turn the dial to the right setting. now, you're ready to test a pcb with a multimeter. The first two digits indicate the resistance value—while the third digit is the multiplier. resistor color code for 330 ohms. for example: “482” = 48 x 100 ohms = 4.8 kiloΩ. if the resistors have values less than 100Ω, you can write it as: “480” = 48 x 10 0 (which is equivalent to 1) = 48 x 1Ω = 48Ω or 48rΩ. 2. how to read resistor color code. reading the resistor color code might seem daunting at first, but it’s a straightforward process once you understand the system. resistor color codes consist of a series of colored bands that represent the resistance value, tolerance, and sometimes the temperature coefficient. let’s break down the steps. 1. identify the colors: note the color of each band from left to right. 2. decode the digits: match the colors to their corresponding digits using the color code chart. 3. calculate the resistance value: combine the digits obtained from the first two bands and multiply them by the multiplier indicated by the third band.

You will see the symbol for a resistor. the abbreviation for a resistor "r" followed by a number to identify it on a pcb "r102". next to the symbol you will also see its value "2.2k". this tells you resistor 102 has a value of 2.2k ohm's. ohm's because resistance is measured in ohm's. on a pcb is a completely different story.
