Question

The magnetic flux through
a coil is varying according to
the relation f = (4 t^3 +5t^2 +8t^-3 +5)
Calculate induced Current at t=2s.
& resistance of Coil s 3 ohm​

Answer 1

Answer:

Explanation:

here p.d= df/dt = 12t^2+ 10t -24t^-4 = 12*4+10*2-24/16

               p.d = 48+20-3/2 = 66.5

i = p.d / r = 66.5/3 =22.167A
