The figure shows a square loop L of side 5 cm which is connected to a network of resistances. |
The whole setup is moving towards right with a constant speed of \[1cm{{s}^{-1}}.\] At some instant, a part of L is in a uniform magnetic field of 1T, perpendicular to the plane of the loop. If the resistance of L is \[1.7\Omega ,\]the current in the loop at that instant will be close to: [JEE Main Held on 12-4-2019 Morning] |
A) \[115\mu A\]
B) \[170\mu A\]
C) \[60\mu A\]
D) \[150\mu A\]
Correct Answer: B
Solution :
[b] Since it is a balanced wheat stone bridge, its equivalent resistance = |
So total resistance |
