1) Figure 1 shows a circuit, with C = 1 µF, R1 = 1 Ω, R2 = 2 Ω and ε = 100 V. Suppose the switch S has been open for a very long time. a) What is the status of the capacitor after this long time — charged or discharged? b) Calculate the time constant of the capacitor. Your answer must include a number and its corresponding unit.
