Question

True or false and explain.

Electrons only travel in one direction when a potential difference is applied across a conductor.

An isolated sphere has a capacitance.

The capacitance of three capacitors placed perpendicular with each other is the sum of their individual values.

A superconductor has zero resistance at some temperature.

By convention, the direction of electric current is opposite to the flow of electrons.

The capacitance of three capacitors placed in parallel with each other is the sum of their individual values.

Explanation / Answer

False, depending on sign of potential, elections can travel in either direction.

True, An isolated charged conducting sphere has capacitance.

False, it is not.
