Questions
The magnetic flux linked with coil, in weber is given by the equation, . The induced emf in the coil in the fourth second is
detailed solution
Correct option is A
|e|=dϕdt=ddt5t2+3t+16=(10t+3)when t=3sec,e3=(10×3+3)=33Vwhen t=4sec,e4=(10×4+3)=43VHence emf induced in fourth second =e4−e3=43−33=10VTalk to our academic expert!
