Question

Two coils (1) & (2) are placed as shown in figure. Coefficient of mutual induction between (1) & (2) is M = 6 H. Find induced emf & induced current in coil (2). (R of coil (2) is 4Ω)


A
emf = 24 V, i = 0
loader
B
emf  = 0, i = 6A
loader
C
emf = 24 V, i = 6A
loader
D
emf = 0, i = 0
loader

Solution

The correct option is B emf = 24 V, i = 6A
e=Mddt=6.ddt{4t}=24 volt.
i=VR=244=6A
