The resistance of a dielectric material should ideally be very high, approaching infinity. This is because dielectric materials are insulators and used to prevent the flow of electrical current. A high resistance ensures that the dielectric can effectively store electric charge without allowing current to pass through.
What else can I help you with?
For an insulating material dielectric strength and dielectric loss should be respectively high or low?
For an insulating material, the dielectric strength should be high to withstand high voltages without breaking down. Conversely, the dielectric loss should be low to minimize energy loss due to internal friction within the material when subjected to an electric field.
Difference between insulation resistance and dielectric strength?
INSULATION RESISTANCE: The insulation resistance is a measure of the capability of a material to withstand leakage of current under a Vdc potential gradient. DIELECTRIC STRENGTH: The dielectric strength is a measure of the ability of the material to withstand a large field strength without electrical breakdown, and is usually expressed in volts per mil (.001') or volts per cm of dielectric.
What is thermal loss in dielectric heating?
Thermal loss in dielectric heating refers to the energy that is dissipated in the form of heat due to the electrical resistance of the dielectric material. This heat loss can reduce the overall efficiency of the heating process and may lead to overheating issues if not properly managed. Techniques such as choosing appropriate dielectric materials and optimizing the design of the heating system can help minimize thermal losses.
Why is insulator called dielectric?
An insulator is called a dielectric because it is able to store and support an electric charge without conducting electricity. Dielectric materials in insulators have high resistance to electric current, which allows them to be used as a barrier against the flow of electricity in electrical circuits.
What is the difference between conductor and dielectric?
Conductors conduct electricity or heat, energy a Dielectric is essentially an insulator.This has nothing to do with juvenile literature. by the way, waxed paper has a Dielectric of 540,00 Volts per Cubic centimeter, as determined by l909 engineering manuals. I will not reveal how I learned that!

Do capacitors have internal resistance?
1. The capacitor has Lead resistance in series with the capacitor2. Since most capacitor use Dielectric and they have a leakage resistance and it is parallel to the Ideal Capacitor.

What is insolation resistance?
I think you mean 'insulation resistance'. This is exactly what it says it is, it is the resistance between opposite sides of an insulator or dielectric. It is in the order of megohms and, in the case of a cable, is inversely proportional to its length -i.e. the longer the cable, the lower its insulation resistance.

Why silicon dioxide used in MOSFET instead of any other material which have high k-dielectric?
Because the gate terminal should highly resistive..silicon dioxide has high resistance and hence gate current is very very low...

How can you test the dielectric strength of oil of transformer?
dielectric strength is tested by transformer dielectric strength oil testing machine. at first, oil which is to be tested is pour near the two electrode. both the electrode should be dipped in oil . then adjust the distance between the electrode .now start the machine.when a sound came from machine then note down the dielectric strength of the oil.
