What’s your favorite value of resistor? 1K? 10K? They’re all fine, but when you need nearly no resistance at all, nothing beats the good old zero-ohm resistor. Wait a minute! Resistors are ...

The security flaws on this common hotel keycard lock are nothing short of face-palmingly stupid. Look closely at the picture above. This is a hotel room door swinging open. The device he holds in ...

Messing around with Arduino can lead to some fun projects-- like simple electronic games, lighting or audio manipulation, or even gesture controls for other devices. However, you'll need the right ...

The inventor Otis Frank Boykin, known for inventing the wire precision resistor, was born on August 29, 1920 in Dallas, Texas ...

While the required external Ls and Cs (of course) vary wildly from topology to topology and chip to chip, (almost) all use exactly the same basic two-resistor network for output voltage programming ...

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 ...

Moving the position of the slider on this resistor, changes the length of wire in the circuit which changes the resistance. A variable resistor is used in some dimmer switches and volume controls.

Biomass represented 8.6% of the UK’s energy supply in 2022 and is set to play an important role in the government’s plan to ...

Our Circuit Design Calculators for Engineers and Students are free-to-use tools that help you quickly determine key parameters ...
