Electric Circuits An electric circuit contains a battery that produces a voltage of 60 volts (V), a resistor with a resistance of 13 ohms, and an inductor with an inductance of 5 henrys (H), as shown in the figure on the following page. Using calculus, it can be shown that the current I=I(t) (in amperes, A) t seconds after the switch is closed is,
(a) Use this equation to express the time t as a function of the current.
