Electrons posses -ve charge and the movement of these charge nothing but current.

Electrical current flow is the movement of electron from lower to higher potential.

But if you considered p-type semiconductor or uni polar device lik mosfet the current is due to flow of holes(+ve charge)too. so why can't the answer be option c ie charge?

Jayanth said:   1 decade ago
Uni-polar means it can carry only one type of charge carriers so he doesn't ask one type charge carrier.

Hole is a vacancy means absence of -ve charge, which is created at the place of electron when it leaves its original place, it's not a particle like proton.

Charge can be the ans as the current flow may be of holes movement.

Current is defined as flow of charge. The electrons charge is negative (-) to flow the negative to positive.

Current is nothing but flow of charge not only electrons. If we consider electrolyte in which current is due to the flow of ions rather than electrons.

Saurav mohan said:   1 decade ago
Answer must be charge. Because in semiconductors current is due to holes and electrons both. Holes are the absence of electrons which keeps shifting to give a flow of current. Hall experiment has also proved that holes exist. Hole is actually a controversial concept. And in electrolytic batteries current arises due to flow of ions.

What voltage refers to?
