Question

In a coil of resistance of 10 ohm the induced current developed by changing magnetic flux

Answer 1

Answer:

Explanation:

Induce current I = e/R

Here e = induced emf = d×magnetic flux/dt

I= e/r = d×magnetic flux/dt

d× magnetic flux = IRdt

Magnetic flux = IRt

It = area under I-t graph

= 1/2 × 4 × 0.1= 0.2

Magnetic flux = IRt

= R × 0.2

= 10×0.2 ( R= 10)given

= 2wb
