The temperature coefficient of resistance of a
conductor is 0.0025/°C. At 200 K its resistance is
4 ohm. The resistance of the conductor will be 8 ohm
at temperature about
(1) 400 K
(2) 300 K
(3) 600 K
(4) 800 K

Answer:
Let R1 be resistance in First case and temperature be t1.
let at t2 temperature resistance will be r2.
.and temperature coefficient of resistance be alpha.
now Given.
R1= 1 ohm
R2 = 2ohm
t1= 300K = 27°C .
t2= ?.
see picture!!for solution!!....
since !!.
option d is correct...
hope it helped you!!....
