What happens to electrons when they pass through a light bulb?
What happens to electrons when they pass through a light bulb? The electrons enter the light bulb filament with relatively high kinetic energies. As they travel through the filament they collide with metal atoms transferring mush of their kinetic energy to the metal. This energy raises the temperature of the metal. Which energy is used […]
