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.
What happens if a lengthy cable is connected to a load?
resistance will increase because we know that resistance is directly proportional to length.AnswerThe increase in resistance will cause an increase in the voltage drop along the cable; if this is excessive, then a cable with a greater cross-sectional area must be used to compensate. Howto choose an appropriate cable for a given length can be determined from the relevant wiring regulations for your country.
What happens to insulation resistance when increasing cable length?
The insulation resistance remains the same throughout the entire length of the conductor.
What isw the Purpose of thermal conductivity in soil during cable laying?
The cabling to Earth is done for electrical conductivity, not for thermal conductivity. The general idea is to get rid of excess charges.
What is the Dimensional formula of thermal resistance?
no

Which has the greater resistance thick wire or a thin of the same length?
The thermal resistance of a wire is proportional to ln(r2/r1), meaning that a thicker wire has a greater thermal resistance.
What is thermal risistance?
Thermal resistance is a measure of a material's ability to resist the flow of heat through it. It is used to quantify how well a material can insulate against heat transfer. A lower thermal resistance value indicates better thermal insulation properties.
Which cable has less losses?
Thicker cable loses less thermal energy.
Is acrylic a good thermal insulator?
No, acrylic is not a good thermal insulator. It has low thermal resistance and can allow heat to transfer easily.
What are some examples of items with low conductivity?
Thermal resistance: diamond Electrical resistance: copper Optical resistance: quartz
What is the term fornmaterials that have very low thermal energy and resistance?
The term for materials that have very low thermal energy and resistance is insulators. Insulators prevent the transfer of heat and electricity due to their high electrical resistance and low thermal conductivity. Examples of insulators include rubber, glass, and plastic.
Define Internal Resistance?
The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
How do you measure the final resistance of a power cable?
A cable power or otherwise has no final or beginning resistance unless power is applied. therefore no unswer to the question
What increases the?
The thermal vibration of the atoms in the material increases the resistance of that substance. The resistance is greatly depends on temperature.
What are the sources of resistance to change?
A: There is only one source thermal
