A parallel-plate capacitor has an area of 100 x 100?m^2 .
a) Calculate the capacitance values for two distances between the electrode plates: 1 and 0.5 µm. The medium is air.
b) If the bias (voltage) in (a) is 3V, what is the attractive force?
c) What is the capacitance if the entire gap (d =1 µm) is filled with water? What is the implication for chemical sensing?
