Question

19. Explain mechanism of glowing bulb? Or Give two examples of poor conductors of
electricity​

Answer 1

Electricity flows through a thin tungsten wire in the light bulb called the filament. The filament used in a bulb has a property called "resistance." Resistance is the amount of friction that an object will put against electricity flowing through it. A filament has a lot of resistance to electricity. Therefore as a result of this, the filament heats up and starts glowing, converting electrical energy to light energy. This is because of the Joule-effect, which means that resistances heat up when electrical current runs through them
