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 ...

To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer. Suppose a manufacturer recommends a maximum voltage ...

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 ...

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, one of the most fundamental concepts to understand is how to calculate the voltage drop across a resistor. Voltage drop refers to the decrease in voltage as it ...
