Current Sensing Resistor Circuit at Domingo Wright blog Circuit Diagram Current Sensing Tutorial: Introduction This project attempts to provide a brief review of the current sensing techniques underlying 2 common types of current sensors: the conventional DC current sensor and the hall-effect sensor. Breadboard 1 To provide a convenient workspace for the circuit . DC Motor 1 Acts as a load in the tested circuit
Ways to measure current: 1- Indirect method: such as current transformers (in the figure) and Hall effect sensors, which relies on Faraday's law of induction to sense current in a circuit and convert it to a proportional voltage. These methods are suitable more for high current systems. 2- Direct method: which relies on Ohm's law which states that V = I x R.

Current sensor circuits are used extensively in systems such as battery management systems in order to detect the current to monitor for overcurrent, a short circuit, and the state of charge of the battery system. so that you don't create a dangerous circuit. So how a current sensor works is that it's put in series with the circuit.
fundamentals of current sensing circuits. It introduces current sensing resistors, current sensing techniques and describes three typical high-side current sensing implementations, with their advantages and disadvan-tages. The other current sensing implementations are beyond the scope of this application note and reserved challenges associated with designing an accurate current-measurement circuit for cost-optimized applications. Approaches range from using general-purpose operational amplifiers to analog-to-digital converters, whether stand- This e-book was created to further simplify the current sensing design process by helping you quickly and efficiently
