Small current measurement

Webb9 okt. 2024 · Current flow is one of the most common parameters used for evaluating, controlling, and diagnosing the operational effectiveness of electronic systems. Because … Webb1 apr. 2024 · The most straightforward is to remember Ohm’s law: a current (I) flowing through a resistor (R) will generate a voltage (V) across the terminals of the resistor, simply calculated as V = R × I. So, a simple shunt resistor can transform a current into a voltage, and this voltage can then be measured by an oscilloscope.
