The potentiometer is often used for audio control. What we'll discuss: I Circuit Symbol of Variable Resistor II Typical Structure of Variable Resistor III Classification of Variable Resistor 1. Film-type Variable Resistors 2. Wire Wound Variable Resistor IV Physical Characteristics of Variable ...
The resistance value is specified in ohms, the standard symbol is “R” orΩ. Resistor values are often stated as “k” (kilo, or times 1,000) or “M“, (meg, or times 1,000,000) for convenience. There are a few conventions that are followed, and these can cause problems for ...

Electrical Resistor Circuit Symbol There are two main circuit symbols used for electrical resistors. The most common symbol for a resistor is a zig-zag line which is widely used in North America. The other circuit symbol for a resistor is a small rectangle widely used in Europe and Asia, and...
For each of these types, astandard symbolexists. Another breakdown based on the material and manufacturing process can be made: Carbon composition Carbon film Metal film Metal oxide film Wirewound Foil The choice of material technology is specific to the resistor purpose. Often it is a trade-off...
Variable A quantity capable of assuming any of a set of values. Identifier To associate oneself with or admire something, such as a set of ideas A language learner who identifies with a new culture. Variable A symbol representing such a quantity. For example, in the expression a2 + b2 = ...
A symbol representing such a quantity. For example, in the expression a2 + b2 = c2, a,b, and c are variables. Variable Able to vary or be varied. Variable winds or seasons; a variable quantity; a variable resistor Variable Likely to vary. Variable Marked by diversity or difference. Vari...
When you turn up the resistance, the electric current flowing through the circuit is reduced. With less current, there's less energy to power the loudspeaker—so it sounds much quieter.Photo: "Variable resistor" is the very general name for a component whose resistance can be varied by ...
