    Answer:

    The complete option for the question

    a.it depends on the self induced emf

    b it depends on the inverse of the self induced emf

    C.it depends on the current

    d.it depends on the inverse of current

    Answer is.it depends on the current

    Explanation:

    The energy stored in an inductor is W=1/2LI^2

    From this equation it can be seen that energy in inductor L depends on current L

    Answer:

    It depends on the current

    Explanation:

    The formula for the energy stored in an inductor is W =1/2 *L*I2

    We can state that an electric current flowing in inductor , there is energy stored in the magnetic field. let consider the pure inductor L, and the power which is supplied to initiate the current in inductor.

    consider the equation P = i*v

    write the equation in terms of inductor.

    P = L*i di/dt

    P*dt = L*i di

    rewrite the Energy equation W = \int_{0}^{t}P*dt

    W = \int_{0}^{t} L*i di

    by solving we will get the W = 1/2 *L*I2

    From this information and formula we can state that he energy stored in an inductor depends on the current.
