Let's say this is our cell. And it's given that across the ends of the cell, across the terminals of the cell the potential difference is three volts. And to calculate work done from this number we need to first understand what this number really means. So we have seen in a previous video that volt really means joules per coulomb.

WebAns: In this case, the work done on the cycle by the road will be equal to the work done by the stopping or the frictional force on the cycle due to the road. The angle between the stopping force and the displacement is 180 degrees. So, now the work done by the road is-. W = F d cosθ. W = 200 × 10 × cos180.
