the low resistivity of a conductor

the potential difference across the ends of a conductor

12.In the presence of an electric field, the free electrons

move in the direction of the electric field

move in all random directions

move at a constant speed

get accelerated in the direct of electric field

13.In an electric field, the acceleration of an electron is

a = mE/e

me/E

a = eE/m

e/mE

14.The direction of the conventional current corresponds to the direction in which
