Inductance between a polyurethane surface

[JeffMandell]

I am interested in creating an electric circuit that travels through a polyurethane surface. My plan is to set up two electrodes separated by the dielectric material.

My question to the wisdom of the internet is how much current will be lost through the polyurethane surface. I am looking for both a qualitative and a quantitative for me to fully understand.

Polyeurathane is an insulator? Your description suits a capacitor more than an inductor. Why not set it up and measure it?

If it conducts at all - no current will be lost through the surface.
The rate that charge enters one side is the same (steady state) as the rate that charge leaves the other side. It may lose energy on the way through though.

Polyeurathane is an insulator?

Indeed. Some types are used as potting/conformal coating compounds to add mechanical stability and improve physical shock resistance of electronic circuits.

You will be hard pressed to make a circuit small enough to 'travel through' any solid.

no current will be 'lost'. [If it 'goes missing', you can find it.]

I can provide some insights on the inductance between a polyurethane surface in an electric circuit. Inductance is a property of a material that describes its ability to store energy in the form of a magnetic field. It is measured in units of henries (H) and is affected by the geometry and composition of the material.

In the case of a polyurethane surface, the inductance will depend on the thickness and composition of the material. Generally, polyurethane is considered to be a low inductance material due to its low electrical conductivity. This means that it will not significantly affect the flow of current in the circuit.

However, it is important to note that even low inductance materials can still have some impact on the circuit. This is because as the current flows through the material, it will generate a magnetic field which can interact with the electrodes and affect the overall performance of the circuit.

To determine the amount of current that will be lost through the polyurethane surface, a quantitative approach would involve calculating the inductance of the material using its dimensions and composition, and then using this value to calculate the amount of energy that will be stored in the magnetic field. This can then be compared to the total energy in the circuit to determine the percentage of current that will be lost.

A qualitative approach would involve considering the properties of polyurethane and how they may affect the flow of current. For example, polyurethane is a non-conductive material, so it will not allow the flow of current through it. This means that any current that does pass through the material will be lost in the form of heat due to resistance.

In conclusion, the inductance between a polyurethane surface in an electric circuit will depend on the material's properties and dimensions, but it is generally considered to be low. However, it is important to consider the potential impact on the circuit and take measures to minimize any loss of current.
