Question:

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

[1 – e (R/L¥] R


If E = 12 volts, R = 10 ohms, and L = 5 henrys, how long  does it take to obtain a current of 0.5 ampere? Of 1.0 ampere? Graph the equation.
