Question

If the change in the magnetics flux linked with the coil is wb/sec .What is the emf induced in the coil of 100 number of turned​

Answer 1

Explanation:

ANSWER

Change n in magnetic flux Δϕ=1−10=−9 Weber

Time taken Δt=0.1 sec

So, emf induced in the coil E=−

Δt

Δϕ

⟹ E=−

0.1

(−9)

=90 Volts
