Technician A says that a WIF sensor uses a couple of probes that measure the dielectric properties of water versus that of fuel. Technician B says that dielectric properties refers to electrical resistivity. Who is correct?
A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B

Question

Quizplus · Accepted Answer

Dielectric properties refer to the ability of a material to store electrical energy in an electric field. Electrical resistivity is a measure of the resistance of a material to the flow of electric current. While dielectric properties and electrical resistivity are related, they are not the same thing. A material with high dielectric properties will have low electrical resistivity, and vice versa.
