Only 5 the rest are correct

...................................

A circuit is constructed with four resistors, one capacitor, one battery and a switch as shown. The values for the resistors are: R₁ = R2 = 46 02, R3 = 99 and R4 = 135 Q. The capacitance is C = 72 µF and the battery voltage is V = 12 V. The positive terminal of the battery is indicated with a + sign. A C 1) The switch has been open for a long time when at time t = 0, the switch is closed. What is 14(0), the magnitude of the current through the resistor R4 just after the switch is closed? 5.65*10^-2 A Submit 2) What is Q(), the charge on the capacitor after the switch has been closed for a very long time? 305.5 UC Submit + 3) After the switch has been closed for a very long time, it is then opened. What is Q(topen), the charge on the capacitor at a time topen = 691 µs after the switch was opened? 286 UC Submit (+) 4) What is IC,max(closed), the current that flows through the capacitor whose magnitude is maximum during the time when the switch is closed? A positive value for the current is defined to be in the direction of the arrow shown. 3.85*10^-2 A Submit + 5) What is IC,max(open), the current that flows through the capacitor whose magnitude is maximum during the time when the switch is open? A positive value for the current is defined to be in the direction of the arrow shown. A Submit
