Potentiometer Circuit Diagram Class 12. To know more on types and application of potentiometer visit byju s. Of two cells and potential difference across a resistor.
This circuit is assumed to be a secondary circuit. If you need a simple resistor that you can change the resistance of you only need two pins. 1 cell a device to maintain a steady current in an electric circuit is electrolytic cell.
To compare the emf s of two given primary cells using a potentiometer.
The above image shows a simple circuit to dim an led. The above image shows a simple circuit to dim an led. The number on the front of the pot tells the highest level of resistance that the pot can achieve. Potentiometer is a device used to compare the e m f.
