Questions tagged [electronic-load]
An electronic load (sometimes called an "e-load") is a device which simulates an electrical load, often as a way to test a circuit's behavior under various load conditions. Many e-loads can be programmed to act as a constant resistance, constant current, constant voltage, or constant power load.

0V with Electronic Load and CC Buck
Why would an electronic load show 0 V and a big current when connected to a constant current source?
The load is in constant current mode. Is that the culprit? Probably a constant impedance would be ...
