Explanation:
Electrons move from higher potential to lower potential. When a conductor is connected to battery, electron move from negative terminal to positive terminal. As current is flowing through it , it means charges are flowing along its length therefore heir must be some electric field parallel to the length of the wire.
Electrons will flow against the electric field lines because their charge is negative, and the electric field thus exerts a force F=qE on them which is in the opposite direction. Thus electric field lines inside the wire go from the positive to the negative terminal and the electron flow goes from the negative to the positive terminal. Electric current goes, consistently with both of the above (because the electron charge is negative), from the positive to the negative terminal.
The electric field lines will twist with the conductor if you bend it into some weird shape. (This is due to slight charge buildups on the wire bends and is beautifully explained by Purcell.) For the situation you describe, the electric field lines and the wire pretty much match already so just draw some more lines.
