ElectroMagnetic InductionHard
Question
The flux linked with a coil at any instant ′t′ is given by
φ = 10t2 - 50t + 250
The induced emf at t = 3 s is
φ = 10t2 - 50t + 250
The induced emf at t = 3 s is
Options
A.190 V
B.-190 V
C.-10 V
D.10 V
= - (20 t - 50) = - 10 voltMore ElectroMagnetic Induction Questions
