According to the morden concept of the atom which are located in the nucleus of an atom

Protons & Neutrons are always located in the center of a nucleus. Protons are positively charged particles and Neutrons have a neutral charge.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
