Question

what does negative sign indicate in potential gradient formula.​

Answer 1

$\begin{gathered}{\Huge{\textsf{\textbf{\underline{\underline{\purple{Answer:}}}}}}}\end{gathered}$

$\implies$If the value of potential gradient is kept high in Power systems then it may affect the person by touch potential.

Note: The negative sign denotes that potential increases in the opposite direction of the electric field vector. A physical example of this situation is the equipotential surfaces.
