1 MQ 2 9 V 4.7 UF WW 56 kQ Determine the following: (a) Assuming the capacitor voltage is 4V when the switch is moved to position 1, what is the capacitor voltage 7 seconds after the switch is moved to position 1? (b) Assuming the capacitor voltage is zero when the switch is moved to position 1, how long does it take the capacitor to charge to 2 V
