The potentiometer is a position tranducer. It forms a resistance divider, proportional to position.
Variable resistance.
Zero to 100 ohms.
A: A potentiometer is a manual device to change the resistance A thermistor changes as a function of environment temperature
A voltmeter is used to measure voltage. A potentiometer is used to vary the amount of resistance in a circuit - it has nothing to do with measuring.
The resistance of a potentiometer can be adjusted by turning the knob or slider on the potentiometer. By changing the resistance, the volume of the speaker can be controlled.
The wiper sets the effective resistance of the potentiometer.
The potentiometer is a position tranducer. It forms a resistance divider, proportional to position.
Variable resistance.
It is a resistor which resistance is changeable, such as a potentiometer.
A linear potentiometer is a potentiometer that changes linearly with rotation of the knob. A 30% degree turn will change the resistance 30%. It's a direct relationship. This is in contrast to log potentiometers, which change resistance logarithmically with turns in the knob.
Copper wire is not used in potentiometers because copper is highly conductive and would not provide enough resistance for the potentiometer to function properly. Instead, materials with higher resistance, such as nichrome or a graphite-based material, are used to create the variable resistance needed in a potentiometer.
it represent the resistance where it can be increased or decreased
A potentiometer is limited by it value(resistance) , it's wattage ( heat dissipation factor) and it's physical size.
Zero to 100 ohms.
