A conductor of length 5 cm, and resistance 2Ω is moving on frictionless rails with a constant velocity of 5 cm/s in a magnetic field of intensity 3 tesla as shown below. If conductor is connected to a circuit as shown, by two lead wires of almost negligible resistance, then current flowing in it is
0.25 A
2.5 Amp
2.5 mA
0.25 ×104 amp
Induced Current -
-
All the 4 resistance are in parallel
Refistance of conductor = 2
1 and 2
are in series
Emf induced across conductor = Blv
