Question

In the figure is shown another circuit that can be used to model a cell membrane. In this particular model, the plates of the capacitor (inside the plastic shell shown in the picture) represent the inside and outside of the membrane while the batteries represent different ion channels within the membrane. The opening of different ion channels is modeled by varying the resistances; these changes in the resistance then cause a change in the potential difference between the capacitor plates. For this problem, we will only consider fixed values for the resistances. All of the questions below refer to the circuit in its "steady state", meaning that the charge on the capacitor is constant and neither increasing nor decreasing.

For each battery, use a potential difference of 5 V (the orange end is the high potential end). Resistor 1 is 14 Ω and resistor 2 is 5 Ω. The capacitor has a capacitance of 0.16 F.

1. What is the current flowing to the capacitor?
I_C = _____ A

2. What is the current flowing through resistor 1 and what direction is it flowing?
I_R1 = _______ A, ---Select--- upward downward

3. What is the current flowing through resistor 2 and what direction is it flowing?
I_R2 = ______ A, ---Select--- upward downward
