If this cell is a neuron, using the voltage clamp to change the cell membrane potential from -70.0 mV to -5.0 mV should cause:
a. A current that indicates that sodium continues to enter the cell as long as the membrane potential is set to -5 mV
b. A current that indicates a large amount of sodium briefly entering the cell
c. No change in sodium current cross the cell
d. A current that indicates a large amount of sodium briefly leaving the cell
