When the current is small, we choose the carbon film type. The electrolytic variable resistor is most suitable for large current, whose electrodes are immersed in conductive liquid. A potentiometer is a special variable resistor for measuring the magnitude of an unknown voltage or potential ...
The word “varistor” is a combination of the words “variable” and “resistor,” and in simple terms that is exactly what this component does: it resists electricity based on how much energy is coursing past and that energy’s intensity. Its main role is to act as more or less of asp...
Chapter 1 - Resistor Fundamentals The resistor is a passive electrical component that creates resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found. The resistance is measured in ohms (Ω). An ohm is the resistance that occurs whe...
A Resistor is an electrical device that resists the flow ofelectrical current. It is a passive device used to control, or impede the flow of, electric current in an electric circuit by providing resistance, thereby developing a drop in voltage across the device. We need some way to control ...

Variable winds or seasons; a variable quantity; a variable resistor Variable Likely to vary. Variable Marked by diversity or difference. Variable (mathematics) Having no fixed quantitative value. Variable (biology) Tending to deviate from a normal or recognized type. Variable Something that is variab...
Apotentiometeris a variable resistor. If you add the potentiometer in series with the LED, you can turn the knob of the potentiometer to adjust the brightness of the LED. Light-Emitting Diode Colors LEDs come in many colors. Common colors are red, green, yellow, amber, blue, and white. ...
An identifier is a name given to elements in a program, whereas a variable is a type of identifier that stores values.
A resistor (also known as an electrical resistor) is defined as a two-terminalpassive electrical elementthat provideselectrical resistanceto current flow. Resistance is a measure of the opposition to the flow of current in a resistor. The larger a resistor’s resistance, the greater the barrier ...
