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.
What are the valve symbols used in piping?
Commonly used P&ID symbols (Piping and Instrumentation Diagram symbols) for manual valves.

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.
Is -8 8 80 8 the additive identity property?
No, -8 8 80 8 is not the additive identity property. The additive identity property states that for any number a, the sum of a and zero is equal to a. So, 0 is the additive identity, not -8 8 80 8.
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.

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 is the transformers 2 about?
It is about the fallen being betrayed by the primes and trying to take his revenge by turning on the Sun Destroyer. But before that, he is planning to get the matrix of leadership because it turns on the machine and it is hidden inside the tomb of the primes. So, as a revenge, megatron, the fallen, and others are trying to get out the symbols in sam's head and to kill the last prime (optimus) by following the symbols and the Autobots trying to stop the Fallen.
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.
If t is less than s and s is less than r what is the relationship between the values t and r?
Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question. Please edit your question to include words for symbols and resubmit.It is necessary to know what the missing symbols are, because they will determine whether or not the relationship is transitive. If the relation ~ is transitive, then t~s and s~r imply that t~r. However, there are many simple relationships which are non-transitive.For example,if t is the additive inverse of s, and s is the additive inverse of r then t is not the additive inverse of r: it is r. Multiplicative inverses behave similarly.if t is the square of s, and s is the square of r, then t is the fourth power of r. Multiples [ t = 5*s] behave similarly.
