Solve this plzzz.. Q.4. Current through the coil varies according to graph then then induced emf v/s time graph is (1) (2) (3) (4) Share with your friends Share 1 Vijay Shankar Yadav answered this Dear Student, Here in the figure there are three straight lines1. i=at2. i=-bt+c3. i=at+dhere a,b,c and d are constant let inductance of the coil is LSo emf for firte=-dφdt=-Ld(at)dt=-Lafor second e=-Ld-bt+cdt=Lband similarly for third e=-LaSo 2 option is correct Regards 0 View Full Answer
