The equation governing the amount of current I (in amperes) after time t (in seconds) in a single RL circuit consisting of a resistance R (in ohms), an inductance L (in henrys), and an electromotive force E (in volts) is

(a) If E = 120 volts, R = 10 ohms, and L = 5 henrys, how much current h is flowing after 0.3 second? After 0.5 second? After 1 second?

(b) What is the maximum current?

(c) Graph this function I = I₁(t), measuring I along the y-axis and t along the x-axis.

(d) If E = 120 volts, R = 5 ohms, and L = 10 henrys, how much current I₂ is flowing after 0.3 second? After 0.5 second? After 1 second?

(e) What is the maximum current?

(f) Graph the function I = I₂(t) on the same coordinate axes as I₁(t).
