What are the different electrical symbols?
In electrical engineering there are many types of symbols used to notate devices. These include symbols for polarity, switches, diodes, and batteries.
Why distribution and power transformer are rated in mva?
Transmission transformers are rated in mva. Distribution transformers are rated in kva. Power transformers are measured in va. There are, of course, exceptions, but this is the normal nomenclature.Answer (for UK terminology)In the electricity supply industry, the name 'power transformer' is used to describe those transformers used in the transmission system (400/275/132-kV levels), while 'distribution transformers' are those used in the distribution system (33 & 11-kV and 400-230-V levels). Power transformers and primary-distribution transformers are rated in megavolt amperes (MV.A), while secondary-distribution transformers are rated in kilovolt amperes(kV.A).Note that 'mva', 'kva', and 'va' are incorrect symbols for 'megavolt ampere', 'kilovolt ampere', and 'volt ampere'. The correct symbols are shown in the above paragraph (except that the period, or full stop, should be placed above the line).However, I suspect your question is really asking why are transformers rated in (mega) volt amperes rather than in (mega) watts? The answer is simply that the load that a transformer can supply is determined by the product of the transformer's rated secondary voltage and rated secondary current -the product of which (for alternating current) is the volt ampere, not the watt.
What are visual symbols?
Visual symbols are symbols that you see everyday in day life and you recognize and know its meaning right away.

How can you use addition of integers to subtract integers?
Subtracting an integer is the same as adding the additive inverse. In symbols: a - b = a + (-b), where "-b" is the additive inverse (the opposite) of b.
What symbols are used for designating the polarity of magnetic poles?
N for North, S for South. W for West. E for East.
What is the simularitie between the Mayan and Roman number system?
The Mayan and Roman number systems have some notable similarities despite their different cultural contexts and bases: **Use of Symbols**: Both systems use a set of symbols to represent numbers. The Mayans had a combination of dots, bars, and a shell symbol, while the Romans used letters from the Latin alphabet. **Additive Nature**: Both systems are additive in nature. In the Roman numeral system, numbers are formed by adding values of symbols together (e.g., VI = 6, which is 5 + 1). In the Mayan system, values are also accumulated by adding symbols together (e.g., a dot represents 1 and a bar represents 5, so three dots and one bar represent 8). **Positional Value**: Both systems have a positional aspect, though they use it differently. The Mayan system is a vigesimal (base-20) positional system, where the position of a symbol indicates its value multiplied by increasing powers of 20. The Roman system, while not strictly positional, uses subtractive notation in some cases (e.g., IV for 4, IX for 9). **Historical and Cultural Significance**: Both numeral systems played crucial roles in their respective cultures for recording and performing calculations, reflecting the advanced understanding of mathematics in these ancient societies. Despite these similarities, the fundamental differences lie in their bases (base-20 for the Mayans versus a more additive and subtractive base system for the Romans) and their symbols and notation methods.
Is -8 8 80 8 the additive identity property?
Probably not, but it is difficult to be sure because of the limitations of the browser used by Answers.com. We cannot see most symbols.
What is the purpose of the electrical symbols?
It depends on the type of electrical symbols. There are safety and warning symbols as well as symbols for identifying parts and their polarity. The symbols are needed for maintenance for proper safety, part identification, and to know how to hook up things. It's much more convenient to have a symbol that everyone recognizes for, say, a resistor, than to glue a resistor onto the wiring diagram.

What are the similarities of the Mayan and the Roman number system?
Both the Mayan and Roman number systems are non-positional, meaning the value of a symbol does not depend on its position within the number. Both systems use additive and subtractive principles to represent numbers. Both systems lack a symbol for zero, which can make calculations more challenging compared to the modern decimal system.

Why ujt have this type of symbols?
The symbols in the unijunction transistor show its internal configuration. The emitter (arrow) represents the polarity. When it points in that is a P type transistor. Pointing out is an N type. The the table on its side the table top touching the emitter (arrow). Its' "legs" are the connection to two bases in the device. It does not have a collector.

What property is -6xy 0-6xy?
If the question was -6xy = 0 - 6xy, then it is the additive identity property of 0. However, due to limitations of the browser used to post questions, most symbols are not visible to us. It is, therefore, difficult for me to be sure what your question was. Hoped I guessed correctly.
