As we say definition of current is flow of charges then why we give the direction of current from +ve to -ve????

by

1 Answer

Answer :

Current flow is like water, water flows from higher level to lower level. Same thing with current, current flows from higher voltage to lower voltage level. The flow of current is in opposite direction of the electron, electron flow from -ve to +ve and current flow from +ve to -ve.

Thanks,then we should have to change the definition of current.because current is flow opposite to flow of electrons.it may definition of conventional current.

Why is it that protons are not considered a source of moving charges for current flow?

Description : Why is it that protons are not considered a source of moving charges for current flow?

Last Answer : Protons themselves are not mobile positive charges because they are tightly bound in the nucleus of the atom and cannot be released except by nuclear forces. Therefore, a current of positive charges is a flow of  either positive ions in liquids and gases or positive holes in semiconductors.
