Question

Consider a capacitor which initially has stored.charge O. it is then connected in the circuit diagrammed below, At time t = 0, the switch S is closed and the capacitor begins to discharge Answer the following questions. What is the voltage drop across the capacitor. before the switch is closed? immediately after the switch is closed a long time after the switch is closed? What is the voltage drop across the resistor before the switch is closed? immediately after the switch is a closed? A long time after the switch is closed? Suppose you added a resistor of resistance 2B in series with the existing resistor. How would the following quantities across the capacitor. The time constant.
