this is because there will be more collisions between atoms and electrons as there is a greater distance to travel. The longer the length of wire, the more collisions. It is like a traffic jam, the longer the road, the loner you are stuck in it for.

∙ 9y agoAs the length of a conductor decreases so does the resistive value of the conductor. Conductors are rated in ohms per foot. To find the resistance of a conductor multiply the ohms/foot by the length of the conductor. As the ohmic value of the conductor increases so does the voltage drop on the conductor due to the resistance of the conductor. At a point the conductor has to be increased in circular size to bring the resistance back down to workable losses. It is this process that determines what size wire is to be used for specific load amperages.

What happens to insulation resistance when decreasing cable length?

What ia Standard of dc loop resistance of copper cable?
It depends on the length of th cable and the diameter of the copper cable used.
What is LV cable insulation resistance acceptance value?
The minimum acceptable insulation resistance value is calculated using the following formula: Rinsulation= (Vrated + 1 ) x (304.8 / L ) Where: Rinsulation is the minimum acceptable insulation resistance value, in mega-ohms; Vrated is the rated voltage of the cable (typically printed on the cable), in kilovolts; and L is the length of the cable, in meters (if the cable length is in feet, replace the number 304.8 with 1000).
How do you calculate volt drop with length and resistance?
cable length multiply with the design current and multiply again by mV/A/m (check on site guide) then devide it by 1000. then u will get the volt drops. BY; MAMERGA
What is the cable size for a 1500 kVA generator with cable length of 50 meters?
35 KVA generator using for load 100 meter length which cable need to used
What happens to insulation resistance when increasing cable length?
The insulation resistance remains the same throughout the entire length of the conductor.

What will happens to current when cable length increases?
With a constant voltage and increase in wire length will increase the end to end resistance and therefore the current will decrease.
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 the resistance when the length is double?
whenever the cable lengthened so is the resistance, their proportional to each other
What is the relationship between insulation resistance and length of conductor in transformers?
when length is increased insulation resistance of cable is decresed i.e.,R is inversely proportional to L where R is resistance L is length
What ia Standard of dc loop resistance of copper cable?
It depends on the length of th cable and the diameter of the copper cable used.
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 is LV cable insulation resistance acceptance value?
The minimum acceptable insulation resistance value is calculated using the following formula: Rinsulation= (Vrated + 1 ) x (304.8 / L ) Where: Rinsulation is the minimum acceptable insulation resistance value, in mega-ohms; Vrated is the rated voltage of the cable (typically printed on the cable), in kilovolts; and L is the length of the cable, in meters (if the cable length is in feet, replace the number 304.8 with 1000).
Define the thermal resistance of a cable?
No. Conductor resistance is. Cable insulation resistance to ground is inversely proportional to its length. The longer the cable, the more leakage path to ground; therefore, the lower the insulation resistance to ground.
What happens to the value of insulation resistance of a cable when the cable gets older?
Insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one megohm. For example, a motor rated at 2,400 volts should have a minimum insulation resistance of 2.4 megohms.
How do you calculate volt drop with length and resistance?
cable length multiply with the design current and multiply again by mV/A/m (check on site guide) then devide it by 1000. then u will get the volt drops. BY; MAMERGA
