Variable resistors, also known as potentiometers, are electronic components that allow the user to change the resistance to the flow of current in a circuit. These components are found in a wide range of applications, from audio equipment to electrical instruments.
Before purchasing a variable resistor, it is important to understand the different types available and their respective uses.
Linear potentiometers have a linear relationship between the position of the wiper and the resistance value. This means that the resistance value changes at a constant rate as the wiper is rotated. Linear potentiometers are commonly used for volume controls and in scientific instruments where a linear relationship between the input and output is desired.
Logarithmic potentiometers, also known as audio taper potentiometers, have a logarithmic relationship between the position of the wiper and the resistance value. This means that the resistance value changes slowly at first, then more rapidly as the wiper is rotated. Logarithmic potentiometers are commonly used in audio equipment for volume and tone controls because human hearing responds logarithmically to changes in sound level.
Multi-turn potentiometers have a higher resolution than single-turn potentiometers because they have multiple turns to adjust the resistance value. This makes them suitable for applications that require precise adjustments, such as in scientific instruments or audio equipment.
Cermet potentiometers are made of a ceramic-metal composite and have a lower temperature coefficient than other types of potentiometers. This means that their resistance value changes less with changes in temperature, making them suitable for use in environments where the temperature varies widely.
Wire-wound potentiometers are made of a wire wound around a ceramic or plastic core. They have a high power rating and are suitable for use in high-power applications, such as in power supplies or amplifiers.
Carbon film potentiometers have a carbon film coating on a ceramic or plastic core. They are low cost and suitable for use in low-power applications, such as in audio equipment.
When buying a variable resistor, there are several factors to consider to ensure that the component is suitable for the application.
The resistance value is the most important factor to consider when choosing a variable resistor. The resistance value of the potentiometer should match the requirements of the circuit. Variable resistors are available in a wide range of resistance values, from a few ohms to several megaohms.
The power rating of the variable resistor is another important factor to consider. The power rating indicates the maximum amount of power that the potentiometer can safely dissipate without being damaged. The power rating should be higher than the maximum power that will be dissipated in the circuit.
The tolerance of the variable resistor indicates the maximum deviation from the nominal resistance value. The tolerance is specified as a percentage of the nominal resistance value. For example, a potentiometer with a tolerance of 5% and a nominal resistance value of 1 kilohm could have a resistance value between 950 ohms and 1050 ohms.
The temperature coefficient of the variable resistor indicates how much the resistance value changes with changes in temperature. The temperature coefficient is specified as a percentage per degree Celsius. A potentiometer with a temperature coefficient of 100 ppm/°C means that the resistance value changes by 0.1% for every degree Celsius change in temperature.
The mounting style of the variable resistor determines how it is mounted onto the circuit board or chassis. The most common mounting styles are through-hole and surface mount. Through-hole mounting requires holes to be drilled into the circuit board to mount the potentiometer. Surface mount potentiometers are soldered directly onto the surface of the circuit board.
The shaft length and diameter of the variable resistor determine how it can be attached to a knob. The shaft length should be long enough to accommodate the thickness of the panel or enclosure that the potentiometer will be mounted in. The shaft diameter should match the diameter of the knob that will be attached to it.
Variable resistors are electronic components that allow the user to change the resistance to the flow of current in a circuit. When purchasing a variable resistor, it is important to consider the type, resistance value, power rating, tolerance, temperature coefficient, mounting style, shaft length, and diameter. By choosing the right variable resistor for the application, you can ensure that the circuit operates as intended.
