As in your lab, a capacitor of capacitance C1 charged to V9 with a charge of On. and an uncharged capacitor of capacitance O; with no charge. are suddenly Cl C2 Vi1ilid=0 connected to each other as shown. Neither is ViiHFVt' connected to a battery. The wires have a small QIHIIIaFQD E J thtial=n resistance, but don't worry about that until part c). a) [5 points] What is the voltage across the capacitors alter they are connected? Answer in terms of V9, C1, and Ca. b) [5 points] For this part take C1=C2=C. If Uinml is the total stored energyr before connection, and Um. is the total stored energy after connection, nd the numerical value of the ratio Umai' Uinm. c) [5 points] Capacitors are charged as before, but they are connected through a resistor that models the wire resistance (again C,=C2=C). After connections are made at =0, the current through the resistor is I() = (Vidia; / R)e-2/RC Write an expression for the instantaneous R power dissipated in the resistor at time t. Vinitial=Vo C Vinitial=0 Useful relation: (et ) =e24 Qinitial=Qo Qinitial=0 d) [5 points] Use the time-dependent current to calculate an expression for the total energy dissipated by the resistor. Useful relations: (e ) =ez, fertfadi =-de-tia
