Induced current

  1. Aug 2, 2010 #1
    1. The problem statement, all variables and given/known data
    A bar of 1 m length aligned in y direction moves in +x direction at 10 m/s, in space where B = 1 T pointing in the -z direction. Calculate the motional EMF.
    If the bar above, is a part of a circuit with a light bulb of 10 ohms resistance, what would be the induced current?

    2. Relevant equations
    emf= vBL
    I dont know what to use to find the induced current

    3. The attempt at a solution
    I know how to find the emf. I found that to be 10 V. Am i correct on that? I am just confused on how to find the induced current

    Hi manda2110, welcome to PF.

    The current in the circuit is

    I = V/R, where V is the induced emf.

    R is given in ur problem (the resistance of the bulb, 10 ohms)
    u know V,
    wheres the problem in finding I???
