Question

198. Answer the following: (a) Among Silves and Coper, which one is a better conductor and why n) Which material would you
advise to be used in electrical heating devices and why? (5)​

Answer 1

Answer:

Hey mate here is your answer

Among silver and copper silver is the best conductor of electricity

Because a material whose resistivity is low is a good conductor of electricity since the resistivity of silver is low than copper, that is why silver is better conductor than copper.

b) Nichrome

Nichrome is the best material for heating elements. It is because the resistivity of the Nichrome is more than tha resistivity of metal used to make it and it does not oxidise at higher temperature.
