True or False Physics Question.

Explain the reson why true or false in detail.

a) the direction of the current I in a metal wire is the same as the direction of the internal electric field in the wire but it is opposite to the direction the electrons are moving.

b) If the potential is constant on a surface, then any electric field present can only be perpendicular to the surface.

c) In a discharging rc circuit, it takes one time constant for the capacitor to discharge completely.

d) If there is an electric field inside of a conductor, then current must be flowing through this conductor.

e) In the metal wires of a circuit, the electron current i flows from the negative to the positive end of a battery, but the current I flows from the positive to the negative end of the battery,
