hi, electric filed is a vector and electric potential is scalar. Gradient of electric potential give us electric filed - plz explain by which space we can describe both quantities.
thanks

They are different ways of describing the same thing - what do you mean by "explain by which space we can describe both quantities"?

i mean electric field needs vector space -so what do we do for electric potential as it is scalar.

Both their domains are open subsets of $\mathbb{R}^{3}$; only their codomains differ.

Can you rephrase your question in a more careful way?
