Solve the all parts of given question:
Question: A 100 pf capacitor and a 400 pf capacitor are each charged to 2kv. They are disconnected from the voltage sources and are connected to each other- positive plate to positive plate and negative to negative.
Part A: What is the equilibrium voltage of each capacitor?
Part B: By how much did the energy of the system change?
I need help to find the equilibrium voltage of each capacitor.
