deals with study of
electricity or electrical is
transmiting the electricity
while electronic is science
which deals with study of
behavior of semiconductor
matals
in electrical conductor is
nessesary for transmiting
the power where in
electronics we use
semiconductor for
generating the signals

why transmission is only 3 phase and not 2 or 4 or poly phases

Sir, My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs. Sir, My question now when my mind strikes with 2 options 1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or 2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2 Please suggest me sir
