We often need some low value resistors, less than 1 Ohm. Mostly as current sensing resistors in power electronics projects. You can't measure less then 1 Ohm with cheap multimeters. […]
LM317 constant current source circuit design
A constant current source source can supply a fixed current to a load regardless of input voltage or load change. LM317 constant current source is one of the simplest design. […]
