Problem deal with the la circuit of Fig. 2.7.7, a series circuit containing an inductor with an inductance of L. henries, a resistor with a resistance of R ohms, and a source of electromotive force (emf), but no capacitor. In this case Eq. (2) reduces to the linear first-order equation.

Suppose that the battery in Problem 2 is replaced with an alternating-current generator that supplies a voltage of E(t) = 100 cos 60t volts. With everything else the same, now find I(t).

Reference of Problem 2:

Given the same circuit as in Problem 1, suppose that the switch is initially in position 2, but is thrown to position 1 at time t = 0, so that I(0) = 0 and E = 100 for Find I(t).
