Question

A circuit is constructed with four resistors, one capacitor, one battery and a switch as shown. The values for the resistors are: R1 = R2 = 48 Q, R3 = 117 and R4 = 127 . The capacitance is C = 56 uF and the battery voltage is V = 24 V. 1) The switch has been open for a long time when at time t = 0, the switch is closed. What is 110), the magnitude of the current through the resistor R1 just after the switch is closed? 0.1371 A Submit Your submissions: 0.1371 Computed value: 0.1371 Submitted: Wednesday, March 11 at 10:04 PM Feedback: Your answer has been judged correct; the exact answer is: 0.137142857142857. 2) What is 11(), the magnitude of the current that flows through the resistor R1 a very long time after the switch has been closed? 0.071 A Submit Your submissions: 0.071 Computed value: 0.071 Submitted: Wednesday, March 11 at 10:05 PM Feedback: Your answer has been judged correct; the exact answer is: 0.0705882352941176. 3) What is Q(), the charge on the capacitor after the switch has been closed for a very long time? 652.24 uc Submit
