Sir practice test 2 - for the chapter you taught on friday - last question - Q10
states that :
temperature coefficient of a wire is a PER DEGREE CELSIUS. At temperature T K resistance is 5 ohm.. At what tempearure will the resistance of the wire be 10 ohm.
I got this question incorrect sir.
In the given solution it is mentioned that since the temp is given in kelvin you convert into celsius. Hence T- 273 and the answer having a three digit no.
I got option 3 - which is when u dont convert into celsius. I dont understand why we are converting thhe temp into celsius... when :
I DEGREE CELSIUS = 1 DEGREE KELVIN
I am confused - pls help me out !
