Those bands tell you the value of the resistor. Before you can decode the resistor value, you need to know a little more about resistors. There are two main types of resistors: Standard resistors have four color bands. Three of the bands tell you the nominal value, which means the value...
Jestine Yong’s How to Find a Burnt Resistor Value will teach you a secret method to find out the value of a damaged and unrecognizable resistor so you will never have to turn down a repair request just because you cannot figure out a single number that will let you know which replacement...
However as you can see, you always need to know two of the quantities before you can work out the third quantity. From looking at the Google Analytics statistics and the questions which land people on this webpage, I often see questions asked such as "how many watts are in 480 volts?"...
resistanceTesting: UsingA multimeterOr measure the resistance value of the component with a resistance tester to determine whether its conductivity meets the specification requirements. Especially forresistorpotentiometerResistance testing is essential for electronic components. capacitanceTesting: measured using a...
The charge has to work hard to move along, which heats up the filament, causing it to glow. In building wiring, the hot wire and the neutral wire never touch directly. The charge running through the circuit always passes through an appliance, which acts as a resistor. In this way, the...

Thank you in advance. To is the initial time. Tact is the TRIAC activation time. Teval is the evaluated time or final time. R is the resistor value. f is grid frequency, and the rest is self explanatory.
But reviewers -- professionals and average users -- either love the tool or hate it, and some people question whether it's really "new" at all. We wanted to know exactly how a Cold Heat tool works, so we took one apart. In this article, you'll learn Cold Heat's secrets, as well...
Step 1: Double Confirm the Resistance of the Resistor Even thought the value of the resistance is printed, you still need to confirm whether the actual resistance is the same as shown. Most resistor has 10% tolerance in their actual value, but it still depends on the type of resistor you...
It's a foundational element of device integrity, but you wouldn't be the first person to beg the question, "What is a UPS?" In short, a UPS safeguards electronic devices from power disturbances and instability. But, of course, there's a lot more to it than that. Contents What Is ...
