AC is normally referred to as active and neutral, while DC is referred to as positive and negative. "Can you represents three phase ac?" not sure what you mean here.
Each of the three phases are active ( positive ) so you could not represent one of them with negative. Hope this helps.
That would be negative three. A negative multiplied by a negative is a positive. A negative multiplied by a positive is still a negative.
Negative because product of 47 negative numbers is negative and product of three positive number is Positive , so negative*positive = Negative.
It is a positive. When you multiply a negative and a negative, it becomes a positive, then you multipy the positive with the other positive
negative 15 plus positive three = negative twelve -15 + +3 = -12
Negative 5. It's normal division, except you need to remember these rules: Positive & Negative = Negative Positive & Positive = Positive
Single phase supply alternates like a sign wave, from negative to positive, producing a less reliable source of power, where as three phase is effectively three lots of single phase source, within the time of a standard single phase source. Each of the three phase sources are 120 degrees out of phase, producing a more consistent power source which can carry greater loads.
The product of three positive numbers is positive. The product of three negative numbers is negative.
The order in which the voltage of the coil reaches to the maximum value is called the Phase Sequence.POSITIVE PHASE SEQUENCE: If the coil is rotated in anticlockwise direction, the phase sequence will be Positive Phase Sequence, i.e., R-Y-B or A-B-C.NEGATIVE PHASE SEQUENCE: If the coil is rotated in clockwise direction, the phase sequence is called Negative Phase Sequence, i.e., R-B-Y or A-C-B.NOTE: Phase Sequence is of great importance in parallel operation of three phase transformers and alternators.
Negative three.
negative ten
Anything divided by itself is 1.
The three regions of a phase diagram represent the states of matter a substance can exist in under different combinations of temperature and pressure. The leftmost region usually represents the solid phase, the middle region represents the liquid phase, and the rightmost region represents the gas phase.
