Questions
The number of turns in the coil of an AC generator is 5000 and area of the coil is The coil is rotated at the rate of 100 cycles/sec in a magnetic field of The peak value of the emf generated is nearly.
detailed solution
Correct option is B
flux linked linked with a coil is ϕ=nABcos ωtinduced emf e=-dϕdt=nABωSinωtmaximum emf = nABω= 5000x0.25x200πx0.2= 5000x10=15.7x104 VTalk to our academic expert!
