An AC generator consists of a coil of 10,000 turns and of area `100 cm^(2)`. The coil rotates at an angular speed of 140 rpm in a uniform magnetic field of `3.6 xx 10^(-2)T`. Find the maximum value of the emf induced.
Data : `N=10,000, A=10^(2)cm^(2)= 10^(-2)m^(2)`,
`v=140 rpm=(140)/(60) rps`,
`B = 3.6xx10^(-2)T, E_(0)=?`

Text Solution

Verified by Experts

`E_(0) = NAB omega = NAB 2 pi v`
`=10^(4)xx10^(-2) xx 3.6 xx 10^(-2) xx 2 pi xx 7/3`
`E_(0) = 52.75` V
