Question

What is meant by saying that the potential difference between two points is 1 V?

Answer 1

Potential difference

1. The potential difference among both two places along a circuit is the difference in the quantity of energy that starts charging bearers have.
2. Whenever work is done on a charge sufficient alters its potential energy, the electric potential difference is the difference throughout electric potential (V) seen between the final and beginning position.
3. Potential difference (P) is measured in $\mathrm{Volts}\left(\mathrm{V}\right)$, and energy (E) is measured in $\mathrm{Joule}\left(\mathrm{J}\right)$.
4. Now, if $1\mathrm{J}$ of effort is necessary to transport a charge of $1\mathrm{C}$ from one place to another, this same potential difference across the two points equivalent to $1\mathrm{V}$.
