Question

(a) What is the current in an 11.00 ? resistor R?

(b) What is the rate of energy dissipation in the resistor?

    (c) What is the mechanical power delivered by the constant force?

A conducting rod of length moves on two horizontal frictionless rails, as in the figure below. A constant force of magnitude 6.00 N moves the bar at a uniform speed of 9.00 m/s through a magnetic field that is directed into the page. What is the current in an 11.00 ? resistor R? What is the rate of energy dissipation in the resistor? What is the mechanical power delivered by the constant force?

Explanation / Answer

a) I =vbl/R

also F = BIL => I^2 = Fv/R = 54/11 => I = 2.21 m/s

b) Q = Fv = 54 j/s

c ) FV = 54 J/s
