The most common approach to current measurement on oscilloscopes is to use current transformers, Rogowski coils or Hall effect clamp-on probes. High-quality magnetic probes are accurate when used within their specifications. They are also convenient when current is flowing in wires or test loops, since they do not require breaking the circuit. However, they have some intrinsic limitations. In this …
There are different techniques for measuring the current flowing in a circuit. Employing Ohm’s law by inserting a shunt resistor of a precisely known value in the circuit is a common and straightforward way of measuring the current in the circuit. This post:
