The symbol is a resistor with a circle around it. There are also two arrows pointing towards it representing the light. Magneto Resistor Magneto Resistor is a special kind of variable resistor, whose electrical resistance depends on the external magnetic force applied to it. Schematically, in ...
This invention relates to variable electrical resistors and is more particularly concerned with small resistors, such as are commonly employed as volume controls in wireless receivers. When such resistors are called upon to withstand frequent relatively large temperature cycles, and the combination......
There’s another important characteristic of a variable resistor which one needs to know before choosing a resistor for a specific application. It is known as the resolution of the resistor. The resolution is nothing but the smallest value of resistance through which a variable resistor changes. A...

Resistors are one of the fundamental components used in electronic circuits. They do one thing: resist the flow of electrical current. There is more than one way to skin a cat, and there is more than one way for a resistor to work. In previous articles I talked aboutfixed value resistors...
Through electrical current does not exceed rated value or practical work needs to be regulation to ensure that the electrical work, usually in the circuit a variable resistor in series. When you change the size of the resistance, so does the size of the current changes, we can limit the cur...
the closing resistor is inserted in series circuit between source and system as the switch is closed and is subsequently stepped out when the switch is fully closed. Closing resistors could be used in any electrical system of any voltage level but are most useful in high voltage or extra high...
