Most Important Selected Qs for JEE AdvancedPhysicsElectromagnetic Induction
An equilateral triangular loop having a resistance R and length of each side ' ' is placed in a magnetic field which is varying at dB dt =1 ~T / s . The induced current in the loop will be
Options
- A3 4 ^2 R
- B4 3 ^2 R
- C3 4 R ^2
- D4 3 R ^2
Correct answer
A. 3 4 ^2 R
Step-by-step solution
aligned & = 3 4 ^2 ~B & = | d dt |= 3 4 ^2 dB dt aligned i= R = 3 ^2 4 R
