Term 1 was provided with choice of choice and 1 out of 4 questions. Only sane number of questions as in cuet but given 2 hrs (cuet will give only 40 min for same no of questions). There is no way you can say term 1 was difficult. Nobody took it seriously and that's the truth. And if you think term 2 was better, result will tell.

How much you got in term 1 ?

Royal Thakur 3 years, 3 months ago

I don't think so bro mine term 2 was better then term 1
just like you and me every student had different opinion about it
So i think either should be 50-50 or one of the best from both

Explain the variation of resistance and resistivity with temperature and hence define temperature coefficient of resistance and resistivity

Posted by Ayush Singh 3 years, 4 months ago

CBSE > Class 12 > Physics

1 answers

Jiya Patel 3 years, 4 months ago

The variation of resistance and resistivity with temperature On considering some materials such as silver ,aluminium, copper consists of number of free electron s flowing through itthis type of materials conduct current easily that means that they are very less reactiveBut the resistivity of the material highly depend upon the temperature .Thus this explains that the metals offer more electrical resistance if temperature is increasedOn the other hand in non metals if the temperature is increased the resistance is decreases Temperature The temperature is a physical property that expresses the degree or intensity of a heat in a substance or matter.
