Question

A straight conductor of length 25cm moves with a velocity of 30m/s in a magnetic field of 0.4T. If the resistance of the conductor is 0.8 Ohm, calculate the current flowing in the conductor.
Options
A 0.72 A
B 1.15 A
C 2.08 A
D 3.75 A
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

emf=BLv=(0.4)(0.25)(30)=3.0V. I=emf/R=3.0/0.8=3.75A.

Hint

emf=BLv=(0.4)(0.25)(30)=3.0V.
