Web pages with pictures are good here - just remember to add lots of your words to describe what you learned through your research.
1) Find a circuit with a potentiometer(s) in it and explain the application of potentiometer(s) in a circuit.
2) What is a rheostat and how does it compare to a potentiometer?
3) Describe the anatomy of a wire-wound potentiometers
4) What is a trimmer potentiometer (or trim pot) ?
5) What does the term potentiometer "taper" mean and what are some examples?
An ac circuit contains a 10.0 Ωresistor, a 6.30 µF capacitor, and a3.70 mH inductor connected in series to anac generator with an output voltage of 50.0 V (peak) and frequency of 1.57 kHz. Find the impedance, the power factor, andthe phase difference..
