Mass is a fundamental unit. Force is fundamental. Do you see a problem with this:
Force = mass * accelation, or
Mass = Force / acceleration
Fundamental quantities are related to each other. There is no contradition to write an equation relating them to one another.
An ampere can be defined as 1A = 1C/second.
Basically VA is the same as watt. Kilo means thousand, Mega (abbreviatted M) means a million.AnswerThe watt and the volt ampere are used to measure two different quantities and, so, cannot be directly converted one to the other. The watt is used to measure 'true power', while the volt ampere is used to measure 'apparent power'.There is, though, a relationship between the two, as the true power of a load is equal to its apparent power multiplied by the power factor of that load. So, if you know the power factor (which can vary from 0 to 1), then you can determine the true power of a load, if you are given its apparent power.Incidentally, SI doesn't recognise either the volt ampere (apparent power) or reactive volt ampere (reactive power); all forms of 'power' are measured in watts in SI. The volt ampere and the reactive volt ampere are best described as 'traditional' units.
well..dead load is calculated by the weight of all quantity of materials used for your slab, beam, column and foundation. though the structure is built from bottom, its analysis is always done from the top..
For a physical quantity to be termed a vector quantity, having magnitude and direction is not enough. The quantity should obey the laws of vector addition too. Like the triangle law or the parallelogram law. As we know, if two currents meet at a junction, the total current of the resultant current will be the algebraic sum of the two current and not the vector sum.Sometimes, treating a current like a vector makes sense, like when the current though a conductor induces a magnetic field.
Throughput andflowrate both express the quantity or a substance per unit time passed through a specific volume. There are two notable differences though. They are that flowrate is usually only used when referring to fluids and throughput is more suitable when considering the feedstock charged through process equipment not just conduit volumes.
Nothing. (You can use this word as identifier though.)
Ampere = Coloumb / second is the same as saying that Coloumb = Ampere x second. Any of the two electrical units can be derived from the other one. Ampere is NOT a "fundamental quantity"; it is an SI base unit. The base units are not necessarily those that are somehow considered more "fundamental" than others; instead, the base units are those that can be measured with a great accuracy. In the case of current vs. charge, it seems that measuring a current can be done with greater accuracy than measuring a charge directly; therefore, the current is the base unit, and the current is derived. However, this doesn't make current any more "fundamental" than charge.
Because you have to start somewhere - you can't derive ALL units. You have to have SOME fundamental units.For example, 1 ampere = 1 coulomb / second. That also means that 1 coulomb = 1 ampere x 1 second, or that 1 second = 1 coulomb / 1 ampere. In other words, you can derive any of the three units from the other two. In practice, for base units, units were chosen that can be measured with great precision.Another AnswerThe ampere is not a 'fundamental' unit; it is a base unit. The ampere was chosen as a base unit, because it relates electrical units to mechanical units, being defined, as it is, in terms of the force (which itself is defined in terms of base units) between current-carrying conductors.You might be getting confused because, quite wrongly, the ampere is often defined as a 'coulomb per second'. While it is certainly equivalent to a coulomb per second, it is not definedin this way.
The ampere is an SI base unit and is not defined in terms of charge and time at the moment. There is a proposal that has been put forward (2005), though still not ratified (2014) that would indeed define an ampere in terms of charge and time. Since the second is a fundamental unit and an electron a fundamental particle it is proposed to define an ampere as the rate of flow of fundamental charges. It is equivalent to 1 coulomb of charge flowing for 1 second. At the moment , the amp(ere) in fact, is defined in terms of the force between parallel, current-carrying, conductors. However, there is uncertainty in this measurement of a few parts in 10,000,000. So, if you were to break down the ampere, you would find it currently is defined in terms of the metre (a base unit) and the newton (a derived unit) which, in turn, is defined in terms of the base units kilogram, metre, and second.
A defining moment for Zachery Taylor was that he became president as an independent even though he was a part of the Whig Party. Another defining moment was that after becoming president, he was anti slavery even though he had previously had slaves.
Yes this happens in case of area. Usually area is a scalar quantity. But we provide the direction of course perpendicular to its plane area we make it as a vector. Same way though electric current is not a vector it is sensed as vector as we put along with length of conductor. I is scalar but Idl is vector.
A ampere is a measure of the flow rate of electricity a coulomb is an amount of electricity. So 1 ampere is a flow of electricity at the rate of 1 coulomb per second.AnswerStrictly speaking, as the ampere is an SI base unit whereas a coulomb is a derived unit, it is more accurate to say that 'a coulomb is an ampere second (A.s)'.With reference to the first answer, the ampere is the SI unit for electric current (not the 'flow rate of electricity', which is meaningless), and the coulomb is the SI unit for electric charge (not the 'amount of electricity'). 'Electricity' isn't a quantity, so it cannot be measured.
No, weight is not a fundamental quantity. Though mass is. The reason for adopting this viewpoint is this: the mass of a body is intrinsic to the body itself - e.g. an electron has the same mass anywhere in the universe. The weight of a body is just the gravitational force acting on that body, and obviously depends on the gravitational field it finds itself in. For example, your mass remains the same if you fly to the moon, but your weight on the moon's surface is roughly one-sixth of your weight here on Earth.
Yes, the ampere is an SI base unit, one of the seven, and equals the passage of a Coulomb of charge per second. Its official definition has to do with force between current carrying wires though.
I is just a sign assigned to represent current in equations and ampere stands for its unit of measurement. So I equals V divided by R where I stands for current, V stands for voltage, and R stands for resistance. And thats just as representation all 3 representations have their own measurement units: For I its Ampere, for V its Volts and for R its ohm's.
Watts is a unit of power, whereas Amperes is a unit of current. They're related though, along with Voltage, Resistance etc. But they're not the same thing, so to answer your question: There are no watts in an ampere! Power (W) = Voltage (V) x Current (I)
Hi,The symbol for amps, or amperes, is A. though in the equation V=IR, current is represented by an I. the proper symbol is A.CommentDo not confuse the symbols for quantities and for units of measurement. Current is a quantity, and its symbol is an italic I. The ampere is a unit, and its symbol is an upright A.
You might call it that; though the term "quantity of matter" is also used for the number of moles. Mass is what gives objects inertia - making it difficult to speed a moving object up, or to slow it down. Mass also gives an object weight in a gravitational field (weight = mass x gravity).
