\(\therefore T _{ b }^{0}+\Delta T _{ b }-\left( T _{ f }^{0}-\Delta T _{ f }\right)=75.7\)
\(\therefore 80+\Delta T _{ b }-\left(5.5-\Delta T _{ f }\right)=75.7\)
\(\quad \therefore \Delta T _{ b }+\Delta T _{ f }=1.2\)
\(\therefore \quad imKb + imKf =1.2\)
\(\quad \therefore i =\frac{1.2}{ m ( Kb + Kf )}\)
\(=\frac{1.2}{0.2(2.65+5.12)}\)
\(\quad \therefore i =0.77\)
