A capacitive sensor is used to measure the level of a non-conductive liquid in a tank. The sensor consists of two vertical parallel plates. As the liquid level rises between the plates, what happens to the overall capacitance?

Question

Answer

The capacitance remains the same because the plate distance is unchanged.

Answer

The capacitance increases because air is replaced by a liquid with a higher dielectric constant.

Answer

The capacitance decreases because air is displaced, reducing the field strength.

Answer

The capacitance is unaffected because the liquid is non-conductive
