yes, its an insulator. its a type of insulator used for wires, cables, etc
Analog signals are transmitted as electrical waves.
because of heat cables expand
One of the single core cables benefits is high current rating. The other benefit is that the operating temperatures of single core cables are least affected by the other cables.
Much of the newer overhead cables is made of aluminum with steel reinforcing it for strenght purposes. Aluminimum is much cheap, and much lighter, thus it is cheaper to use vs. copper for high voltage transmission, and copper has a lower resistance which means more electricity can get through the wire/ cable, which means more electricity can get around the world quicker. most people should use copper becasue it has a lower resistance where aluminuim has a bit of a high resistance not to much but a bit so that is why you use copper not alominuim.
Electrical cables carry electrical energy in the form of electricity. The energy is transmitted through the conductive materials within the cable, such as copper or aluminum wires.
Through cables.
someone smart
no, its just light being transmitted
Light.
Electricity is transmitted at a high voltage of 400000 volts so that it may be able to travel for a long distance.
why?
Electric cables carry electrical energy in the form of electricity.
They're connected by cables. The wind spins the turbine - generating electricity. The electricity is fed into the national grid by cables.
using electricity cables
There are three! (i think)
The colour of the electricity cables!
