An electromagnet can be modeled as an inductor in series with a resistor. Consider a large electromagnet of inductance L = 10.0 H and resistance R = 6.00 Ω connected to a 24.0-V battery and switch as in the figure shown below. After the switch is closed, find the following. A circuit contains a battery, a switch, an inductor, and a resistor. The circuit starts at the positive terminal of the battery labeled emf ℰ, goes through the switch labeled S, goes through the inductor labeled L, goes through the resistor labeled R and ends at the negative terminal of the battery. (a) the maximum current carried by the electromagnet  A (b) the time constant of the circuit  s (c) the time it takes the current to reach 95.0% of its maximum value  s
