Answer / manish kumar singh

It depends upon current and material of cable. Size directly
proportional to the current and inversely proportional to
the conductivity of material.

Answer / bob

from the cable size table we can select the size of it
accourding to the amprage that we have, then increasing the
size of cable depending on distance and the heat temperture
that we need to install.

Answer / lucky

Formula=
p=vi cos@
to find out line current
and according to table
the size of cable.

Answer / senthil.m

first calculate the power,power means voltxcurrent,these
voltage means potential differeence,the current means
electrons electrons means (heat) flows throw conductors so
cable inside heat flows, so answer depens upon the
heat,heat inversalypropotional to the coil,

how can we calculate the current

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
