Resistance Range: The variable resistor has a range of 1 Mega Ohm (1 MΩ), which means you can adjust the resistance from zero ohms to 1 MΩ using its adjustable knob.
Adjustable: The variable resistor consists of a resistive element and a wiper. As you turn the knob, the wiper moves along the resistive element, changing the resistance value.
Potentiometer Type: Depending on the design, it may be a linear potentiometer (change in resistance is linear with knob rotation) or a logarithmic (audio) potentiometer (change in resistance is logarithmic, suitable for audio applications).
Mounting Options: Variable resistors come in various sizes and mounting styles, such as panel mount or through-hole, making them adaptable to different circuit layouts.
Tolerance: Like other resistors, variable resistors have a specified tolerance level indicating the allowable range of deviation from the labeled resistance value.
Applications: 1 MΩ variable resistors are used for volume controls in audio systems, dimmer controls for lighting, gain controls in amplifiers, calibration of sensors, tuning circuits, and wherever precise and adjustable resistance is required.
