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.

In the circuit of Fig. 2.7.7, with the switch in position 1, suppose that L = 2, R = 40, and I(0) = 0. Find the maximum current in the circuit for
