For current to flow there must be some potentialdifference
Now we know that E= -dv/dr, so for electric fieldto lie the dv term i.e. change in potential mustnot be zero.
As current current is flowing inside the conductorthen there must lie electric field too which willmake the electrons move giving rise to current.

First of all you should understand how the current flows through the wire ?
When charges flow through wire , it generates current .
Because current :- flow of charges in wire per unit time is known as current.
To have current , electrons must be accelerated along the wire. Due to accelerated electrons electric force must be act on them , {
because you know two opposite nature charge must apply coulombic force on each other .
Also we know, Force , F = qE ,where q is charge and E is electric field .
Means when a charge particle q placed on eletric field E , it experiences F force}
Hence, due to electric force , field must introduce inside the current carrying conductor.
In simple way, you can say , electric field produced inside the conductor due to accelerated charge flow through current carrying conductor .
