The good news is that a class of clamp meters in the market can accurately measure inrush current. They use high-speed, digital signal processing to filter out electrical noise and capture inrush ...

If you're seeking a way to measure current and power in a circuit, you need to know about current-sense amplifiers (CSAs). A CSA is a specialized op amp connected as differential amplifier with ...
