This video breaks down how resistors work and why they’re one of the most essential components in every electronic device.

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...

This video explains how resistors function and how Ohm’s Law defines the relationship between voltage, current, and resistance in electronic circuits. Resistors are passive components used to control ...

Download this article in PDF format. Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in ...
