1M Ohm Volume Resistor

This 1M ohm volume resistor is a type of variable resistor that is used to control the volume of an audio signal. It has a resistance of 1 million ohms, which means that it allows a very small amount of current to flow through it when the knob is turned all the way down. As the knob is turned clockwise, the resistance decreases, allowing more current to flow through and increasing the volume of the signal.

1M ohm volume resistors typically use in audio amplifiers, radios, and other audio devices. They can also use in other applications where a precise control of volume is require, such as in laboratory equipment and medical devices.
The input voltage of a 1M ohm volume resistor can be anything from a few volts to several volts, depending on the application. In audio applications, the input voltage is typically the same as the signal voltage, which is usually between 0 and 1 volt. When the volume knob turned all the way down, the input voltage applied to the resistor. As the knob turned clockwise, the resistance of the resistor decreases, allowing more current to flow through and reducing the voltage at the output of the resistor. The output voltage of the resistor is then use to control the volume of the audio signal.

The maximum input voltage that a 1M ohm volume resistor can handle depends on the power rating of the resistor. A 1/2 watt resistor can handle a maximum input voltage of about 50 volts. A 1 watt resistor can handle a maximum input voltage of about 100 volts.

It is important to note that the input voltage of a 1M ohm volume resistor should not exceed the maximum voltage rating of the resistor. If the input voltage exceeds the maximum voltage rating, the resistor may overheat and damage itself.

1M Ohm Rotary Potentiometer is a type of variable resistor that has a rotating shaft. The shaft  connected to a wiper, which moves along a resistive track. As the shaft turned, the wiper moves along the track, changing the resistance between the shaft and the two terminals.

Here are some of the benefits of using a 1M ohm rotary potentiometer:

• Resistance: 1 million ohms
• Power rating: 1/2 watt or 1 watt
• Taper: Linear or logarithmic
• Shaft size: 6mm or 8mm
• Knob: Included or sold separately
• High resistance: A 1M ohm potentiometer has a very high resistance, which makes it ideal for applications where precise control of a signal required. 
• Durability: Rotary potentiometers typically made of durable materials.
• Wide range of applications: Rotary potentiometers can use in a wide variety of applications, including audio equipment, industrial controls, and medical devices. This makes them a versatile component that can use in a variety of different projects.
• Affordability: Rotary potentiometers are typically very affordable, making them a cost-effective option for many projects.

1M Ohm Volume Resistor Specifications : –

1M ohm rotary potentiometer linear taper potentiometer provides a linear change in resistance as the shaft turned. This means that the change in resistance is directly proportional to the change in shaft position. This makes linear taper potentiometers ideal for applications where a precise control of a signal required.

1M Ohm Volume Resistor Pin Descriptions : –

1M ohm rotary potentiometer has three pins:

• Pin1: This pin is connected to one end of the resistive element.
• Pin2: This pin is connected to the wiper, which is the movable contact that slides along the resistive element.
• Pin3: This pin is connected to the other end of the resistive element.

When the shaft of the potentiometer turned, the wiper moves along the resistive element, changing the resistance between pins 2 and 3. The resistance between pins 2 and 3 is directly proportional to the angle of the shaft.

The three pins of a 1M ohm rotary potentiometer typically labeled as follows:

• Pin1: Common or GND
• Pin2: Output
• Pin3: Reference
