Current-sensing techniques are intrusive, meaning that somehow they will affect the system performance. It’s usually necessary to insert “something” in the middle of the path that goes from the power source to the load through which the current that we need to monitor flows.

Resistor engineers designed to mitigate these losses must use current sensor resistors with low resistive values. This is the greatest complexity of this method, choosing the better resistor to obtain a balance between precision, energy loss, and costs in the current sensor

Construction and Types of Wirewound Resistors

As the name indicates wire-wound resistors consist of a resistive wire wound on a bobbin and supplied with a protective coating. Since the resistance wire never can serve as a termination wire because of solderability requirements, it has to be connected to the terminal leads or the like, usually by welding or brazing. The higher the resistance value the thinner the wire that has to be used and thus the greater the risk of open circuits due to deficient weldings, damage from corrosion or from mechanical handling. Below a diameter, Φ, of 0.1 mm (4 mils) the failure rate grows rapidly.
