Monitoring current on inductive loads is a common task. It's easier to do on the low side of a driving circuit, because a simple resistor can be used with an op amp on the ground rail. The high side often demands that an expensive current sensing transformer or Hall effect sensor be used. High Voltage and Load Current Monitors In applications where output current sensing is required, the voltage monitor circuits described can be modified to measure current. It is quite difficult to employ high side sensing techniques to measure current because of the high voltages involved. As such, only low side sensing circuits are presented here. How to Build a Current Sensor Circuit This is a current sensor circuit, where if we get to a certain level of current, then the output will turn on. And we can build a current sensor circuit, simply by exploiting ohm's law. Ohm's law states that, I= V R, where I is the current, V is the voltage, and R is the resistance.
