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 of3.6 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)=? |
