Resistors are small but essential components that manage how electricity moves through a circuit. This video explains how ...

You may find it tempting to leave decisions on passive component tolerance for the PCB engineer or assembler. If you are going to cut corners on your schematics make sure you understand how component ...

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 ...

Some ideal op amp configurations assume that the feedback resistors exhibit perfect matching. In practice, resistor non-idealities can affect various circuit parameters such as common mode rejection ...

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 ...
