3. During voltage clamp analysis when an electrode is fully submerged in a bath that is very deep, it becomes much harder to adequately compensate for the electrode capacitance.
A. How do you explain this?
B. Suppose you applied a layer of wax to the outside of the electrode so that all but the tip was coated. How would this affect the capacitance of the electrode? (Hint: Look up how capacitance relates to the composition and geometry of the capacitor.) Would this make balancing the bridge easier or harder?
