An iron core inductor is a type of inductor that utilizes a ferromagnetic core made of iron or iron alloys to enhance its inductance and efficiency. It is widely used in various electronic and electrical applications due to its ability to store and release energy in the form of a magnetic field. In this technical description, we will explore the key features, working principles, applications, and advantages of iron core inductors.

Shunts are a type of resistor that is specifically designed to measure current. They work by creating a voltage drop across the resistor as a result of the current flowing through it. By measuring this voltage drop, we can calculate the current passing through the shunt using Ohm's law (I=V/R).
