A Trimpot is another type of potentiometer that comes in small package. It has three leads and can be easily mounted on breadboard or perf board for quick prototyping. The value of the pot can changed by varying the knob on top of it.
Selecting a Potentiometer
Potentiometers also known as POT, are nothing but variable resistors. They can provide a variable resistance by simply varying the knob on top of its head. It can be classified based on two main parameters. One is their Resistance (R-ohms) itself and the other is its Power (P-Watts) rating.
The value or resistance decides how much opposition it provides to the flow of current. The greater the resistor value the smaller the current will flow. Some standard values for a potentiometers that we havein stock are as follows100Ω 220Ω, 470Ω, 500Ω, 1K, 2K, 5K, 10K, 22K, 47K, 50K, 100K, 220K, 470K, 500K, upto 1M.
