The magnetic flux threading a coil changes from `12 xx 10^(-3)` Wb to `6 xx 10^(-3)` Wb in 0.01. Calculate the induced e.m.f.

Text Solution

Verified by Experts

Here, `phi_(1) = 12 xx 10^(-3) Wb, phi_(2) = 6 xx 10^(-3) Wb`,
`dt = 0.1 s = 10^(2)s, e = ?`
`e = (- d phi)/(dt) = (-(phi_(2) - phi_(1)))/(dt)`
`= (-(6 xx 10^(-3) - 12 xx 10^(-3)))/(10^(2))`
`e = 0.6` volt
