Trimmer & Potentiometer
Why are they used?
Trimmer are used for "trimming" the value of a resistor, and are commonly used for calibrating instruments, setting the bias current on power amplifiers, and a host of other areas where a circuit cannot be relied upon to give an exact gain, output voltage, or current.
Applications / How do you spot opportunities?
All Application need triming the Value the Resistance and Calibrate the current by change the resistance.
How to ask for opportunities?
Does your Circuit need to trim the resistance?
