A) 12m/s
B) 14m/s
C) 15m/s
D) 16m/s
Correct Answer: C
Solution :
Ohm's law. V = IR \[\operatorname{R} =\frac{V}{1} = slope of V -1 graph\] Slope for A < B \[{{\operatorname{R}}_{A}}<{{R}_{B}}\] \[\operatorname{Resistance} \propto temperature\] \[\therefore \]resistance increases with increase in temperature \[{{\operatorname{T}}_{B}}>{{T}_{A}}\] \[{{\operatorname{T}}_{2}}>{{T}_{1}}\]You need to login to perform this action.
