Q8 of 10 Page 1

Define 1Volt. Express it in terms of SI unit of work and charge. Calculate the amount of energy consumed in carrying a charge of 2 coulomb through a battery of 7V.

One volt is defined as energy consumption of one joule per electric charge of one coulomb.


Or


1V =


Now, we know that the potential difference between two points is given as:



Or Work done = V × Q


= 7V × 2C


= 14 Joules
