Questions & Answers
Q: What is the Principle of Conversion of Energy?
The Principle states that energy changes from one form to another, like electrical energy converting to heat and light in a light bulb.
Q: Why is the filament of a light bulb made of tungsten?
Tungsten is used due to its high melting point, allowing it to withstand the heat produced by resisting electron flow in a light bulb.
Q: How does hindrance to electron flow cause a light bulb to glow?
Hindering electron flow with the filament creates friction, which heats up the filament and makes it glow due to the energy conversion process.
Q: What role does electricity play in making a light bulb glow?
Electricity flowing in a bulb's filament generates heat and light by overcoming resistance, resulting in the bulb glowing.
Summary & Key Takeaways
-
Light bulbs glow due to the conversion of electrical energy to heat and light.
-
Tungsten filaments hinder electron flow, creating friction that heats up and glows.
-
The Principle of Conversion of Energy explains how a light bulb functions.
