JEE Main 2022 Physics question
The magnetic flux through a coil perpendicular to its plane is varying according to the relation Weber. If the resistance of the coil is 5 ohm, then the induced current through the coil at t = 2 s will be,
Answer: (1)
Solution
The emf is . At t = 2: V, so i = 78/5 = 15.6 A.
