Answer / sushil bagade

if we apply the E.M.F it create the P.D across the ckt and
due to that current is flow in short EMF have ability to
produce potantial difference and due to that electron flow
occure and that is nothing but current flow

Answer / pswin

Conductors have an abundance of free electrons which requires low pressure to move them from one atom to another, and establish a high current. This is the characteristic of conductors and that's why, current can flow through them.

How to find Cable size? Caterpillar generator produce (Two generators) 127*2=254 amp at 11 kv . What would be the cable size (XLPE) to supply 256 amp at 11 kv? Air or surrounding Temperature is 32 degree C. Cable will go under ground at 2.5 feet depth. Group Rating Factors is 3 cables. Clearance between cables is 7 cm. Soil Temperature (Ambient) 28o C Soil Thermal Resistivity is 1.2 K.m/W I would like to use 3 separate single core instead of using 3 core cable. Some says I should use three separate single core 120RM cables. Some says 70RM .some says 95. I m totally confused. Is there ant specific rule to determine cable size? What would be the LT cable size to flow 500 Amp current? Ifte My e mail address is ifte13@yahoo.com Anyone please send me the answer to my e mail address, i will be very glad.
