Q # 1. The potential is constant throughout a given region of space
... Q # 11. Can an electric motor be used to drive an electric generator with output from the generator being used to operate the motor? Ans. No it is not possible. Because if it is possible, it will be a self operating system without getting energy from some external source and this is against the law ...
