- How is converted the energy of a E.M. wave in a conductor

- Relevant Equations
- ##u_i = u_e + u_m##

I'm thinking about how the energy is conserved when a E.M. wave pass through a conductor.

If a E.M. pass through a conductor, the electrons must move "oscillated", thus the energy from the E.M. wave is converted to kinematic energy.

Another way I see that is the E.M wave must generate a current.

I don't know if my intuition is correct, but either way, I can't prove the conservation of energy. The initial energy ##u_i = u_e + u_m \neq u_f + \frac{1}{2}mv^2##

I must forget something or it's not as simple as that.
