In a coil of resistance 150 , a current is induced by changing the magnetic flux through it as shown by figure. The magnitude of flux through the coil is Wb.

Correct answer

300

Step-by-step solution

By Faraday's law of electromagnetic induction, array ll = d d t , Also, =i R & d d t =i R d =i R d t & d =R i d t array =R Area of current versus time =150 1 2 0.4 10=300 ~Wb
