An electrical circuit is arranged as in the picture next to it. The difference in battery potential is known to be 1.2 kV, the capacitor is 6.5 uF and all the resistance is 0.73 MOhm A) If the switch is closed at t = 0, calculate the current in R1! B) If the switch is closed at t = 0, calculate the current in R2! C) When the switch is closed at t = 0, calculate the current at R3! D) After the switch is closed long enough, then the switch is reopened, draw a graph of the relationship between the energy stored on the capacitor as a function of time!
