Electric Circuits An electric circuit contains a battery that produces a voltage of 60 volts (V), a resistor with a resistance of 13 ohms (Ω), 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 I.
- (b) After how many seconds is the current 2 A?
