However, sometimes resistors overheat and burn when they fail to dissipate the high temperature caused by the electric current. When this happens, the color code on the resistor is destroyed and hence you are left unable to figure out how to get the resistor value which is important information...

In a novel twist, the author measures the resistance of a lamp to find its temperature. Onset of electrical resistance measured for first time by Dave Mosher. Wired, December 21, 2011. Physicists find a way to observe how slowing electrons cause resistance. Component of the Month: Resistors ...
We will use the resistors to protect the LEDs. If you fail to use the resistors, the LEDs will burn out immediately. This equipment is not the sort of stuff you are going to find at the corner store. However, it is not hard to obtain these parts. You have a few choices when trying...
With these tables, you can find the digit, multiplier, and tolerance for any color band. Let’s look at some examples decoding 3, 4, and 5 band resistors step-by-step: Resistance Calculation Examples 3 Band Resistor Orange – 3 Orange – 3 Red – x100 3,3 x 100 = 330 Ω ...
The need for finding the power ratings is to find out how much power a resistor can handle, or in other words its power capacity. With increased power rating requirements, a high-size resistor is required. The power ratings are also called the wattage ratings of resistors....
They cost less than 1 cent each, but humble resistors are an essential tool no matter what electronics you are building. In this reference guide we look at using them in projects, and how to identify the correct resistor for your project.
The sensor is connected to anintegrator, an electrical circuit built around aninverting operational amplifier. The inverting amplifier is a complex semiconductor device, made up of a number of transistors, resistors and capacitors. The details of its operation would fill an entire article by itself,...
I'm not able to find how to calculate the value Rsp? Is the resistor Rsp the same value as Rs? Hey Ricardo, Rsp will have a similar calculation to Rs in figure 10. Figure 11 simply shows how to implement a similar circuit t...
A resistor is an electrical component that is used to create resistance in circuits. This resistance can be utilized in many ways, like dividing the voltage or reducing the current. There are many types of resistors. However, the one that we're going to work with in this article is the ...
