Question

dimensional formula of electric potential.

Answer 1

Dimension of electric potential is [ML^2T^-3A^-1]

You can find it from the relation

emf ( potential)=w/Q

[W]=[ML^2T^-2 ]&[Q]=[AT]

Answer 2

The dimensional formula of electric potential gradient is?

Potential energy (P.E.) =

Mass(m) × Gravitational acceleration (g) × Altitude (h).
