Two parallel conducting bars are joined at one end by a resistor with resistance R and separated by a distance d. Another conducting bar of length d slides at constant velocity v along the parallel bars. The bars have a negligible resistance. a) What is the expression of the current flow in the circuit? b) How much power is required to move the bar? c) How does the power dissipated in the resistance compare with the power required to move the bar? d) Explain how the motion of the moving bar affect the induced emf.
