Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I x R.

The output voltage when the wiper is at 0 cm is 0V.
- The wiper is a movable arm that slides across a resistor to change the resistance value.
- The voltage divider rule states that the voltage across a resistor in a series circuit is proportional to its resistance value.
- In this case, the potentiometer acts as a voltage divider circuit with two resistors in series.
- The output voltage of the potentiometer depends on the position of the wiper along the resistor.
- When the wiper is at 0 cm, it is at one end of the resistor and has zero resistance.
- Therefore, all of the input voltage appears across this end of the resistor and none appears across the other end. Hence, the output voltage when the wiper is at 0 cm is 0V.
