In the figure there are two identical conducting rods each of length `a` rotating with angular speed `omega` is the direction shown.One end of each rod touches a conducting ring.Magnetic field `B` exists perpendicular to the plane of the rings.The rods the conducting rings and the lead wires and resistanceless.Find the magnitude and direction of current in the resistance `R`.

Answer

`(B omega a^(2))/( R) ` from C to D
