IB Physics: 5.2-5.3 Electric cells and circuits

There is no potential difference between the two spheres below. They have exactly the same charge distributed over the same surface area (much like there being no gravitational potential differences on flat ground).It would require exactly the same amount of work to take a small positive test charge from infinity to the surface of the left sphere as it would to the right sphere:To make a potential difference we need...
