The resistance between the two stationary contacts is, of course, fixed, and is the value specified for the potentiometer. The photo resistor or photocell is composed of a light sensitive material. When thephotocellis exposed to more light, the resistance decreases. This type of resistor makes...
For an Inductive divider with non-interacting inductors, the equation becomesThe inductive divider divides the DC input analogous to resistor divider circuit depending on resistance and it divides AC input with regard to the inductance. A basic low-pass RC filter circuit is shown below which compris...
At low frequencies (<100 kHz), ferrites are inductive; thus they are useful in low-pass LC filters. Above 100 kHz, ferrites becomes resistive (high Q). Ferrite impedance is a function of material, operating frequency range, dc bias current, number of turns, size, shape, and temperature. ...

Product description: KangYuXin series including ASZ(trapezium shape),ASC (ship shape)and ASCB(ultrathin shape),the mould can get more than 20 species to let resistors suit for environment installa- tion and application. Aluminum resistor is also called brak...
1.Inductor-free:The resistor body is a specific material,and the body is conductive.The inductor is very small,only a few microhenries,which is a few tenths of other types of non-inductive resistance inductors. 2.High current impact resistance:The resistor has a large heat capacity.Compared ...
As the frequency of an applied AC voltage increases, the inductive reactance of the ESL increases to a point at which it is equal to the capacitive reactance of the device, and the capacitor behaves as a resistor. At frequencies above this point, the capacitor is effectively an inductor. ...
if we use a capacitive load without an electric charge it is considered as a short circuit, this will result in ahigh “inrush”of current and when the applied voltage is removed from an inductive load, there will be a large amount of reverse voltage buildup in the circuit when the magn...
nonreactive components do not care about the frequency of the signal entering into the component. They do not change resistance values based on the input frequency. One such component is the resistor, which operates independent of frequency. Whether the voltage going through it is DC or AC doesn...
