Problem

In a liquid level sensor, two parallel vertical plates of height

H = 20\,\text{cm}

and width

w = 5\,\text{cm}

are partially immersed in oil (

K = 3

) to a depth of

h = 8\,\text{cm}

. The remaining upper part is in air. Calculating the equivalent capacitance if plate separation is

1\,\text{mm}
