2. Two resistors, an inductor, and an emf source are connected as shown in the figure. & = 24 V, R1 = 80, R2 = 16 0, and L = 4 H. R1 E R2 L S a. When S is closed at t = 0, calculate the following quantities: i. the current through R1, ii. the current through R2, ed jones viril chollibnow allele menus iii. the current through the switch, iv. the potential difference across R2, scum bleft onloste grippers A v. the potential difference across L, and vi. dil at b. At some time, t, after the switch has been closed, the current in the inductor is increasing at a rate of 2.00 A/s. At this instant, what is the current through R2 and the current through the switch. c. Now, the switch is opened after being closed for a long time. i. What is the voltage across the inductor at t = 0? Determine the high potential side of the inductor (top or bottom). ii. At what time, after t = 0, does the current in L have the value of 1.50 A? 3. A 60-uF capacitor is charged by connecting it to a 12.0 V battery. The capacitor is then disconnected from the battery and connected across a 1.50-H inductor. a. What is the angular frequency of electrical oscillations and the period of these oscillations? b. What is the initial charge on the capacitor? c. How much energy is initially stored in the capacitor? d. What is the charge on the capacitor 0.0230 s after the connection to the inductor is made? Interpret the sign of your answer. e. At the time given in part (d), what is the current in the inductor? Interpret the sign of your answer. f. At the time given in part (d), determine the total energy in the circuit
