Unformatted text preview: current through the inductor after a long time? f) The switch is then opened. Just after the switch is opened what is the potential difference vab across the resistor R1? g) Which point, a or b, is at a higher potential? h) What is the potential difference vcd across the inductor L? i) Which point, c or d, is at a higher potential? 7. A coil is connected to a 60‐Hz, 100‐V AC generator. At this frequency the coil has an impedance of 10 Ω and a reactance of 8 Ω. a) What is the current in the coil? b) What...
