The magnetic flux through a coil with a resistance of 10? changes over time as shown in the figure. Which of the following is the inductance of the coil in Henry at t=3 second? A) 30 B) 20 C) 50 D) 80 E) 150
Given,Resistance of the coil, From the figure, flux changes from to in 4s.Then, So, the flux as a function of time is given by,Then, at t =3 s, flux is,
