When an electric field is applied to a metallic crystal, the movement of electrons is?

When an electric field is applied to a metallic crystal, the movement of electrons is random. Metals form giant structures in which electrons in the outer shells of the metal atoms are free to move. Hope this answers the question. Have a nice day.

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

Sorry i dont understand the question can you rephase it?
