Problem 2 (50 points). Give brief explanations The capacitor circuit shown has been connected for a long time. C1= 4 ULF a. [10 pts] Find the equivalent capacitance of the circuit. Use proper units. Draw simplified 12 V diagrams to explain your work. C3=18 ULF C2=: 6 UF I JCF ) HF b. [6 pts] What is the charge on C1? Use proper units. c. [6 pts] Find the voltage across C1. Use proper units. d. [8 pts] Find the charge stored in C4. Use proper units. e. [8 pts] Find the energy stored in C3. Use proper units. f. [6 pts] If Ci were to be removed from the circuit and replaced by a wire, would the entire circuit now store more charge, less charge, or the same amount of charge as before? The new circuit (C1 removed) stores less / more / the same charge. (Circle one) Explain: g. [6 pts] In the original circuit, if the battery voltage were doubled how would the energy stored in C3 change
