STANDARD Physics AC Generator MCQ Question
Type: MCQ-numerical-Medium-Class 12
A boy peddles a stationary bicycle the pedals of the bicycle are attached to a 400 turn coil of area 0.20 m². The coil rotates at one fourth of a revolution per second and it is placed in a uniform magnetic field of 0.05 T perpendicular to the axis of rotation of the coil. The maximum voltage generated in the coil is
A
6.28 V
B
2.16 V
C
3.24 V
D
3.14 V
Correct Answer
Option A
Detailed Explanation
Maximum voltage generated is ε₀ = NBA(2πν) = 400 × 0.05 × 0.2 × (2π × 0.25) = 6.28 V.
