The lightbulb in the circuit shown in the figure has a resistance of 14 Ω and consumes 4.2 W of power; the rod is 1.18 m long and moves to the left with a constant speed of 2.9 m/s . The strength of the magnetic field is 2.2 T .
Find the current that flows in the circuit.
What speed must the rod have if the current in the circuit is to be 1.3 A?
