An electromagnet can be modeled as an inductor in series with a resistor. Consider a large electromagnet of inductance L= 12.5 H and resistance R = 5.50 connected to a 12.0-V battery and figure shown below. After the switch is closed, find the following. R. (a) the maximum current carried by the electromagnet (b) the time constant of the circuit (c) the time it takes the current to reach 95.0% of its maximum value
