Question

Q---defination of volt

Answer 1

Ans----The potential differnce betwwen two points is said to be 1 volt if 1 joule of work is done in moving 1 coulmb charge from one point to the other point.

1 volt =i joule/i coulomb

v=y/c or V=JC (POWER MINUS 1)

**POTENTIAL differnce is measured by an istrument called as voltmeter **
**Volt meter is always connected parallel across the point where potential differnce to be meaured.
** A volt meter has a high resistance.

Answer 2

when 1 joule of work is done by 1 coulomb of charge, from an infinity to a point in the electric field then the potential at that point is called 1 volt.
