Question

Q 1. Give two properties of copper that make it good for use in electric circuits.
Q 2. Why do some scientists say " Silicon chips are the electronic brains that run the world"?

Answer 1

cooper has free electrons in their last orbit that why he is the good conducter . cooper has least resistivity that why he is a good conductor

Answer 2

HEYA MATE , HERE IS UR ANSWER ____________________________

1. Copper is used in electric circuit because -

a)It has low resistivity and hence a gold conductor of electricity .

b)It is cheaper than silver.

2. Silicon chips are the electronic brains that run the world. They fly our planes, drive our trains, take care of the washing while we are out, keep us alive in hospital and handle our most intimate conversations.
They play a vital role in working of the computer and control all our day -to -day works. So ,some scientists call the 'electronic brains that run the world '.
