3. The circuit contains an ideal battery, two resistors and'a capacitor ( C - 250 uF). The switch is closed at time t - 0, and the voltage across the capacitor is recorded as a mction of time as shown in the graph. Read the data in the graph carefully and answer the following questions. (a) (b) (c) (d) (e) (f) (s) (h) (i) 0') (k) V What is the voltage of the battery? V = What is the time constant for this circuit when the switch is closed? 1: gm - , What is the time constant for this circuit when the switch is open? 1 em = . What is the resistance of the resistor R1? 34 = , What is the resistance of the resistor R2? & = . What is the voltage across resistor R; at t = 2.0 seconds? 2, = I What is the voltage across resistor R2 at t = 2.0 seconds? 'Vg = . What is the total current produced by the battery at t = 0? I = What is the current through resistor R1 at t = 5.0 seconds ? I = ' What is the charge on the capacitor t = 15.0 seconds ? _q_=__. When is the switch opened? t =
