A source of voltage produces an electric current by _____.

Aincreasing resistance in the conducting wire

Bincreasing the speed of electrons that are flowing

Ccreating a potential difference so electrons can flow

Verified Answer :

c.creating a potential difference so electrons can flow

The correct choice is

C. creating a potential difference so electrons can flow.

An electron moves from low potential to high potential. so it moves only when there is difference in potential between two locations. A source of voltage creates a potential difference for the electron to move. So the correct choice is C.
