capacitance a function of height...
the question I find difficult is:
A liquid-level transducer consists of two parallel plates of conductor immersed in an insulating liquid, as illustrated in this figure:

When the tank is empty (i.e., x=0), the capacitance of the plates is 200 pF. The relative dielectric constant of the liquid is 25.
a) Determine an expression for the capacitance C as a function of the height x of the liquid.
I have no idea what do start with?
