Single Phase ac circuit

  1. Jul 13, 2009 #1
    Hi there

    Im new to this site and i have noticed that you give advice to electronic questions. Presently im studing electronics and on some of my course work i am having some difficulty in understanding some of the questions. such as,

    Q1
    A conductor 300mm long moves at a uniform speed of 4m/s at right-angles to a uniform magnetic field of flux density 1.25T. Determine the current flowing in the conductor when:

    a) its end are open-circuited

    b) its ends are connected to a load of 20 ohm resistance

    and,

    Q2
    Calculate the e.m.f induced in a coil of inductance 12 H by a current changing at the rate of 4 A/s

    Any advice or helpfull sites to visit would be much appreciated,

    Thanking you in advance

    Rich

    Welcome to Physics Forums.

    Since you didn't post your questions in the homework section, you're unaware of our policy on this type of question (not your fault).

    Can you provide:

    A. any equations from your class lectures or text book that appear to be relevant to solving the problems, and

    B. provide your thoughts or attempt at solving the problems (doesn't have to lead to a final solution)
