In an electrical circuit, voltage is the force that pushes the electric current through the various components. When current passes through a resistor, some of the voltage gets used up or “dropped” ...

When working with electrical circuits, it is essential to understand how to calculate the voltage across various components, such as resistors. In this article, we will explore the methods for ...

This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t ...

Knowing how to calculate an LED current limiting resistor is one thing, taking into account all other sorts of parameters as well is another. In Part 1 you learned how to calculate a current limiting ...

Many LEDs, those highly popular Light Emitting Diodes, die prematurely because they are improperly used by people who know little to nothing about electronics. Let's try to stop the massacre. An LED ...

High-resistance grounding (HRG) makes a power distribution system safer and more reliable than the alternatives. High-rresistance grounding can limit point-of-fault damage, eliminate transient ...
