Tips: Influence of 50Hz 60Hz exchange to resistive components

Most people usually believe that these components are simply one resistance. Connecting with both AC and DC currents can satisfy its lightening and heating functions. Its power can be satisfied through satisfying the voltage grade requirement. In fact, that is not the case. The lamp and heater are assimilated to regulated conductor(take roundness as an example). The theoretical current is evenly distributed in the conductor. When we supply AC current into it, because of the electromagnetic induction, the electromotive force impending current will be perceived in the conductor center. At this moment, the current tends to the outer ring and outer surface of the conductor. The distribution starts to become uneven. This is a “skin effect” phenomenon. Therefore, it is not hard to infer that, when the voltage is fixed, the frequency exchanges from 50 Hertz to 60 Hertz application, the induced electromotive force increases, the area of the conductor center ring enlarges, the active area of conductor current circulation decreases, the corresponding conductor resistance increases, the current reduces, and the power decreases.
Strictly speaking, it still affects the resistive element. It is sometimes that it does not took into account because the low voltage level does not affect its performance.
