I have often wondered whether the practice of using a ratio of two resistors to determine a particular output is a fundamental property of electronics or a concerted effort by designers. In either ...

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 ...

Although there are several ways to sense current flowing from a source such as a battery, or to a load such as a motor, the current-sense resistor is among the most widely used approaches. There are ...

The fundamentals to translating the analog world into the digital domain reduces to a handful of basic parameters. Voltage, current, and frequency are electrical parameters that describe most of the ...
