Question

Two Loop RC Circuit 1 1 2 3 4 5 6 A circuit is constructed with four resistors, one capacitor, one battery and a switch as shown. The values for the resistors are: R1 = R2 = 47 Q, R3 116 Q and R4 127 Q. The capacitance is C 55 uF and the battery voltage is V = 24 V R2 ww 1) The switch has been open for a long time when at timet 0, the switch is closed. What is 1(0), the magnitude of the current through the resistor R1 just after the switch is closed? A Submit You currently have 0 submissions for this question. Only 10 submission are allowed. You can make 10 more submissions for this question. 2) What is 1(), the magnitude of the current that flows through the resistor R1 a very long time after the switch has been closed? A Submit You currently have 0 submissions for this question. Only 10 submission are allowed.
