High Voltage Resistor
Wirewound resistors have been electrical passive components which limit current with the wire material featuring high resistivity. Their resistive elements exist out of the metallic wire insulated that has been winded around the non-conductive material core.The resistive elements are existing out of metal wire that is insulated and winded around a non-conductive core material. Such resistors have been typically composed of copper-nickel-managese called as the “Manganin” or Nichrome materials (nickel-chromium). These kinds of resistors have been composed of manganese, nickel and copper. It also includes nickel-chromium or Nichrome materials. These wire wound resistors were actually the oldest types of resistors that were still manufactured nowadays. These are produced accurately. Aside from that, they are also possessing excellent low resistance value as well as high power rating properties.
Construction of the wire wound resistors are depending on some factors. This actually involves manufacturing and selection of materials which depend upon the way that the resistor has been used in circuits. The values of resistance rely on wire resistivity. It also involves cross section and length. For higher tolerance measurement, resistance value must be measured. This is to identify the accurate cut for the wire length. To make the resistance high, the diameter of the wire should be small enough while its length must be long.

Current Sense Resistors
Wirewound resistors have been giving capacitance and inductance that are affecting the current flow in an alternative current circuit. Due to the wirewound resistor design principle, which is the inductor, it got the worst frequency properties among other types of resistors. There are different methods of winding application. However, they still vary on the application of the resistor. Through the DC current, there will only be a few problems in terms of winding compared to the AC current due to the self induction and parasitic capacity. Reducing the effects is done in different methods. These include bifilar winding, flat former winding and the Ayrton-Perry winding.
Types of winding are usually associated measurement devices as well as decade banks. However, the downside is more on difficult process of manufacturing. Wirewound resistors come in distinct kinds. They were categorized into power type and the precision type. They were generally modified for many different selections of applications. These applications include temperature sensors, current and potentiometers.
DC Current Shunts
A wire resistor is usually found in a circuit breaker or as a fuse. In order to come up with fusible resistors, the manufacturers are going to integrate small springs into the other end of a resistor. Once the current and the heat through these resistors get too high, the solders are going to melt. This takes place when the springs popped up as the circuit opens.
