explain why an led's brightness is proportional to the electric current flowing through it
Homework Answers
The electrons flow into one end of the metal bulb bottom, they then flow into the filament where they meet heavy resistance. This resistance causes the filament to heat up and produce light as the electrons try desperately to keep moving.

Why does a wire get warm if a current runs through it? A. An electric field in the wire accelerates the charge carriers, increasing their kinetic energy and the thermal energy is nothing but the average kinetic energy of the charge carriers. B.An electric potential difference results in an electric field that accelerates the charge carriers, which frequently collide randomly with stationary atoms, transferring part of their energy to the atoms. C.The charge carriers create an electric field, which accelerates...
