Measurement of Potential difference
Potential difference is nothing but voltage and is measured by a device called Voltmeter. It is always connected in parallel across the points whose potential difference is to be measured.
1 V = 1 J/ 1 C, potential difference is 1 when 1 joule work is done to move 1 coulomb of charge from one point to another
