ELECTROMOTIVE FORCE VS. POTENTIAL DIFFERENCE

the energy supplied to the unit charge by the dry cell

the energy dissipated as the unit charge passes through the electrical components

present even when no current is drawn through the battery

across the conductor is zero in the absence of current

its unit is volt and the symbol is $$\Delta V$$

its unit is volt and the symbol is $$\epsilon$$

It transmits current both inside and outside of the dry cell.

It transfers current between two points in the dry cell.

It causes electric, magnetic and gravitational field.

It induces only in an electric field.
