A switch controls the current in a circuit that has large inductance. If the switch is open but near the point of contact where it would close the circuit, a spark can arc across the switch. Is a spark more likely while the switch is being closed to connect the circuit, or while the switch is being opened to disconnect the circuit? Why? en Shot .50.59 AM 2. Two AC voltages have the same amplitude but different frequencies. Are there rms amplitudes the same? en Shot ...9 AM (2) 3. For the circuit at right: a. Immediately after the switch is closed, what is the current in the inductor? 12V b. A long time later, what is the current through the inductor? c. What is the energy stored in the inductor in part (b)? d. A long time later, the switch is opened. Immediately after, what is the voltage across the inductor? с. 4. In the circuit at right, a 100 mH inductor and a 5 2 resistor are connected by a switch to a 6 V battery. a. After the switch is thrown to position a (connecting the battery), what time interval elapses before the current through the inductor is 200 mA? b. What is the current through the inductor 10 seconds later? c. Now the switch is quickly thrown from position a to position b, such that the inductor and resistor form a complete circuit separate from the battery. How much time elapses before the current falls to 200 mA? R L bo с. 4. An AC current is given by I = 495 sin (9.43t), with I in mA and t in ms.
