Explain the two energy changes that occur in light bulb and fluorescent tubes
Answers
Answer:
When you turn the lamp on, the current flows through the electrical circuit to the electrodes. There is a considerable voltage across the electrodes, so electrons will migrate through the gas from one end of the tube to the other. This energy changes some of the mercury in the tube from a liquid to a gas.
Answer:
In your common incandescent lightbulb you will transform electrical energy into two main forms of energy coming off of the lightbulb.
Heat: from the filament of the bulb because you are running an electrical current through the filament. The heat is so immense that it forms our second form of energy, which is light!
Light: Which is formed from the bright red/yellow glow of the lightbulbs filament. The atoms become excited and give off the light we use everyday.
