i a circuit with a coil of resistance 2 ohms, the magnetic flux changes from 2 wb to 10 wb - Physics - Electromagnetic Induction

Question

i a circuit with a coil of resistance 2 ohms, the magnetic flux
changes from 2 wb to 10 wb in 0 2 second the charge that flows in
the coil during this time is
5 coulomb
4 coulomb
1 coulomb
0 8 coulomb
please help me xperts

Arshad Ibrahimi · Answer

First calculate EMF=-rate of chang of flux=-(2-10)/ 2=40 V
Now I=V/R=40/2=20A i e 20 Columb/sec as I=q/t

i a circuit with a coil of resistance 2 ohms, the magnetic flux changes from 2 wb to 10 wb in 0.2 second. the charge that flows in the coil during this time is 5 coulomb 4 coulomb 1 coulomb 0.8 coulomb please help me xperts
