No manufacturing isn't one of the four instruments of national power
An ammeter and a wattmeter are the instruments needed.
Agriculture, Communication and information, Construction, energy and power, Manufacturing, Madical, Transportation
In hydro power or solar power the energy source is pollution free but the process of manufacturing and building the plant is not of course.
We use the 250 ohms with the power supply because the internal resistance of a DC power supply is insufficient to develop a resistance.
I am not an electrical guy....but since this question was left unanswered....i'll just put in some nonsense!! For AC Load: VxIxPF (V=VoltageRequired, I=Current Required, PF=Power Factor) The Power Factor is normally considered to be 0.8 as a thumb rule. For DC Load: VxI, here the power factor is consisdered to be 1, since it is a DC current !! Byeee!
