    An emf self-induced in a solenoid of inductance L changes. .

    I know how to differentiate the equation, but I don't know how that gives me dI/dt, could you elaborate?

    An emf self-induced in a solenoid of inductance L changes. .

    I know that I have to take the integral of an equation twice, though I do not know how to incorporate L and the given equation into one really.

    An emf self-induced in a solenoid of inductance L changes. .

    An emf self-induced in a solenoid of inductance L changes in time as E=E_0e^(-kt) Find the total charge that passes through the solenoid, if the charge is finite. (Use E_0 for 0, k, and L as necessary.) Now I know that the induced emf is E_L=-L(dI/dt) I'm having a hard time on this...

    How Do You Calculate Electric Potential at Point P from a Uniformly Charged Rod?

    The thin, uniformly charged rod shown in the figure has a linear charge density . Find an expression for the electric potential at P. (Use k_e for ke, lambda for , a, b, and L as necessary.) I'm not sure how to tackle this problem, if anyone could come up with the expression so that I...
