Activity 3.6 NCERT Class 10 Science, Chapter 3 Metals and Non-metals
Activity 3.6 asks us to connect a metal wire with a bulb in series and see what happens to the bulb.
The bulb glows as bright as earlier.
Metals have free electrons in their valance shells. These free electrons move from one position to another. As a result, metals are a good conductor of electricity. When we connect a build to the battery by metal wires, electricity passes from the battery to the bulb. As a result, the bulb starts glowing.
This experiment demonstrates that metal wires are a good conductor of electricity.
In making wires at home, in making electric circuit board etc.
When someone is electrocuted, we do not use a metal stick but we use a wooden or plastic stick. Metal stick or rods are good conductors of electricity. If someone tries to save an electrocuted person by that stick, he himself will get electrocuted.
