Question

How is potential difference calculated?

Answer 1

A unit of positive electric charge must be moved from one spot to another in order to create a potential difference.

To calculate the potential difference between two points:

1. Establish the field's strength, $E$, as well as the separation between the two spots, $d$.
2. Calculate the potential difference between the two sites using the formula $\Delta V=Ed$.
3. Divide the resistance present in the circuit by the current flow rate. The potential difference, expressed in volts, is the outcome of the multiplication. Ohm's Law, $V=IR$, is the name of this equation.

Where $V=$Voltage, $I=$Current, and $R=$Resistance.
