AIPMT MAINS 2012 Physics Faraday's Law MCQ Question
Type: MCQ-numerical-Medium-Class 12
In a coil of resistance 10 Ω, the induced current developed by changing magnetic flux through it, is shown in figure as a function of time. The magnitude of change in flux through the coil in Weber is:
A
8
B
2
C
6
D
4
Correct Answer
Option B
Detailed Explanation
The area under the current-time graph gives the charge, q = 0.2 C. Using q = Δϕ/R, we find Δϕ = 2 Weber.
