Question

Si and cu are cooled at themperature of 300k then resistivity

Answer 1

Sorry dear don't know the answer...

Answer 2

Answer: given Si and Cu are colled to a temprature of 300k resistivity of metall increase with temperature and rasistivity of semiconductor decreases with increasing temperature for metal , R increasing as. T increasing

For metal R decreasing as T increasing

we know Si as semiconductor and CU is an metal so as temperature Resistivity of Si increasing or Cu decrease.

Hope it help you please mark as brilliant

Have a great day ☺️
