This simple but clever continuity tester sports two LEDs: RED LED = circuit resistance is < approx 10K, GREEN LED = circuit resistance <10Ω. It consumes approx 8mA from a 9V battery. When not ...

The simplest model of a battery comprises an ideal voltage source that connects in series with a resistance whose value—often a few milliohms—depends on the battery’s electrochemical condition and ...

Menlo Micro’s Ideal Switch can handle 10 A with a 0.010-Ω contact resistance for power-distribution applications like smart ...

Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are ...
