QUESTION 2: The voltage source in the given circuit has 240 V DC voltage. The capacitor in the given circuit has been connected to terminal d of the three-position switch for a long time. At t = 0, the switch is moved to position e, where it remains for 6 ms. After that, the switch is moved to position of where it remains indefinitely. Please answer the following: (20 pts.) 2.a) Using the general solution method, derive the numerical expressions for the voltage across the capacitor when the switch was moved to terminals e and f (one expression for each switch position). (10 pts.) 2.b) Considering that the initial value of the voltage of the capacitor as 40 V, at what time the voltage of the capacitor becomes 30 V ?
