An armature coil consists of 20 turns of wire, each of area $A=0.09 m^2$ and total resistance 15 Ω. It rotates in a magnetic field of 0.5 T perpendicular to the axis of rotation at a constant frequency $\frac{150}{π}$ Hz. The value of maximum emf produced in the coil is: |
120 V 270 V 940 V 1260 V |
270 V |
The correct answer is Option (2) → 270 V |
