Question

If 20j work has to be done in moving an electric charge of 4c from a place where a potential is 10v to another place where potential is v then find the value of v

Answer 1

$\huge\underline\mathfrak\pink {Solution}$

The potential difference between two points is said to be 1 volt if the work is done in moving 1-coulomb charge from one point to other is 1 joule. Unit for measuring the potential difference is volt and instrument used for measuring potential difference is a voltmeter.
