sir what is emf
Asked by vgadekar873 | 12 May, 2020, 08:34: PM
answered-by-expert Expert Answer

1) emf is the voltage developed by a source of electrical energy like a battery or a cell.
 
2) It is this voltage that drives the current through the circuit.
 
3) The name emf is the abbreviation of "electromotive force". Here, force is not the mechanical force but it is the potential or energy that the cell provides to drive the current.

The flow of electrons is opposite to the direction of the flow of current as electron is negatively charged . Then why current is defined as the flow of electrons through the conductor though current travels from positive to negative terminal.
