"What is the difference between voltage and potential
differnce?"

Answer Posted / mozaffar jawed

VOLTAGE- It is deffind as the product of current &risistent
is known as VOLTAGE. It is SI unit volt.Voltmeter is the
instument used to measer the voltage.
POTENTIAL DIFFERENCE-It is used to measer the voltage b/w
to point of the electric field. It have also SI unit VOLT.
