Find the change in current in an inductor of 10 H in which the e.m.f. induced is 300 V in `10^(-2)` sec. Also, find the change in magnetic flux.

Text Solution

Verified by Experts

Here, `d I = ?, L = 10 H, e = 300 V`,
`dt = 10^(2) sec, d phi = ?`
As `e = (L dI)/(dt)`
`:. 300 = 10 (d I)/(10^(-2)) dI = (300 xx 10^(-2))/(10) = 0.3 A`
Also, `e = (d phi)/(dt) :.d phi = e dt = 300 xx 10^(-2) = 3 Wb`
