Near... Nearish is not a word but you could say that too
a homograph is a word that is spelled the same but has different meanings. so a homograph for close (example for bold close: we are getting close to the border) would be close(example for italic close: close the door)
The term "taut" can be synonymous with tight, tense, or stretched.
in the strictest sense of the word; close as in proximity or close as in shutting something. In a looser sense you could use clothes as a homophone.
The prefix in the word "monotonous" is "mono-," which means "single" or "one." This prefix indicates that something is the same or repetitive.
No, "quiet" is not a homonym. Homonyms are words that sound the same but have different meanings. "Quiet" is a single word with its own distinct meaning.
Not necessarily. Two single-phase supplies could be supplying the same phase, which means you don't get the same range of voltage options you get with a true two-phase supply.
The same as in single phase with the same RMS voltage.
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
A congruent phase transformation occurs when a single phase changes into another single phase with the same composition. An incongruent phase transformation happens when a single phase changes into multiple phases with different compositions.
In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases, or balanced). But don't get available current and available power confused (KVA is not the same as KW).
A single-phase supply needs two wires to allow the current to circulate.
135 A at 120 v single-phase is 16.2 kVA. With a 208 v three-phase supply you get three single-phase 120 v supplies, so the same kVA is produced with a balanced load of 45 amps on each phase.
They will not be very different.

Single phase requires 2 wires - a hot, and a return (both wires of the same size. Three phase requires three (same size), and if it is grounded will require a forth (doesn't normally carry current so it can be small). Two phase requires three wires (two phase conductors of one size, and a return that can handle double the current of the phase conductors), or four wires (same size for all, effectively two separate single phase supplies). It isn't economical is the bottom line. It costs ~the same (in wire) for two phase as three, and you get 50% more power delivering capability with three phase.
If I have 1 KW In 3 Phase it will give 1.54 A and In single phase it will give 4.6 AFor cosF 0.9V 415 3 phV 240 1 phIt seems the reason is because the current is carried on more wires. Also, remember that if wattage stays constant, then as voltage increases, current decreases.AnswerIt really depends on the load. Are you assumining the three-phase load to be the same as the single-phase load or, as it is likely to be in practice, three times the value of the single-phase load?But, in either case, the single-phase current will not be double the the three-phase (line) current!The equation for the load current supplying a single-phase is: I = P / (E x power factor)The equation for the line current supplying a balanced three-phase system is: IL = P / (1.732 x E x power factor)If you insert real figures into these equations, (240 V for the single-phase voltage and 415 V for the three-phase line voltage) then you will find that, when the three-phase load is threetimes that of the single-phase load, the supply currents will be exactly the same. On the other hand, if you assume that the three-phase load is exactly the same as the single-phase load, then you will find that the three-phase line current will be one-third that of the single-phase current.
A homogeneous mixture has the same composition and properties throughout, meaning it consists of a single phase. In contrast, a heterogeneous mixture contains multiple phases with varying compositions and properties.
