The types of windings in wire resistors can be seen in the image below. They are usually designed so that the Inductance of a WW Resistor is negligible compared with the Resistance and the Resistance of and Inductor is negligible, compared with its Inductance. This means that the inductance would be very high, particularly for components with many coils (as we would want for greater resistance).The main difference is that the resistor uses an insulating core to dampen the inductive effects, while an inductor uses a magnetic core to boost the inductive effect.There is a better way to reduce the inductance: you can wind the resistor in such a way as to reduce or eliminate the magnetic field. The Power rating formula of a resistor can be calculated by the simple equation which includes the voltage and current been applied to the resistor.
