the Fan will not run, because principle and construction of
DC and AC motors are different from each other, AC motor
can not run on DC supply. and heating will produce in the
winding of the AC motor. if we supply it DC voltage.

what is tri state logic gate
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

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
