AC stands for alternate current, DC stands for direct
current. Alternate current alternates between positive and
negative and the number of times it does per minute is
called cycles. Depending on the number of poles in the
motor, the speed is constant. Where as in a DC drive, the
speed control is simple, by introducing a resistance.

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
