Question

A coil of resistance 400 ohm is placed in a magnetic field.if the magnetic flux linked with coil varies as fi=50t^2+4 aipmt 2012

Answer 1

Thanks for the question. Please find the answer below:

A coil of resistance 400 ohm is placed in a magnetic field.if the magnetic flux linked with coil varies as fi=50t²+4. The current in the coil at t=2 is 0.5A.

Answer 2

Explanation:

If the magnetic flux Φ (Wb) linked with the coil varies with time t (sec) as Φ = 50t2 +4. The current in the coil at t= 2 s is. 0.5 A.
