defination and explination of potential difference
Potential Difference is the difference in electric potential energy per coulomb of charge at one point of a circuit compared to the charge at another point in a circuit.
Potential difference, or voltage, is a way of describing the energy of an electric field without using test charges. In circuits, potential difference is the difference in voltage from one part of a circuit to another. It can also be described by ohms law where the Voltage=Current*Resistance
OR
THE DIFFERENCE OF VOLTAGE FROM THE REFERENCE SOURCE TO THE LOAD OR A CERTAIN REFERENCE POINT AFTER PASSING THRU A CIRCUIT OR COMPONENTS.
or
In an electrical circuit, potential between two points is defined as the amount of work done by an external agent in moving a unit charge from one point to another.
Mathematically, E=WQ
Where,
E = electrical potential difference between two points
W = Work done in moving a change from one point to another
Q = the quantity of charge in coulombs
The potential difference is measured by an instrument called voltmeter. The two terminals of a voltmeter are always connected parallel across the points whose potential is to be measured.
