What is the correct way to abbreviate kilo volt ampere kva Kva kVA?
It is common to see each of the examples used. However the technically correct way is kVA.AnswerFollowing the conventions of SI for compound units, a dot should be placed between the 'V' and the 'A', above base level: that is: kV.AThe symbols for units named in honour of individuals are always capitalised, so the symbol for volt is 'V', and the symbol for ampere is 'A'.Having said that, the symbol generally used for reactive volt amperes is var. So I suppose one could argue as neither the volt ampere or reactive volt ampere are really SI units, then they don't really have to follow SI conventions!
What is one way you can measure energy?
with volt meters
A coulomb is a measure of whereas an ampere is a measure of .?
Is a coulomb a measure of quantity whereas an ampere is a measure of rate?AnswerThe coulomb is the SI derived unit for electric charge. The ampere is the SI base unit for electric current.The coulomb is defined in terms of the ampere and the second. The ampere is defined in terms of the newton and the metre.
What is 1 ampere equal to?
Among other things, 1 ampere is equal to:1 coulomb / second1 volt / 1 ohmBasically, you can understand 1 ampere as a certain amount of electric charge (1 coulomb) flowing past a certain point per second (although in the SI, the definitions are the other way round: the coulomb is a unit derived from the ampere).
Is a coulomb a measure of quantity whereas an ampere is a measure of rate?
Yes. The Coulomb is the SI unit of electric charge, and it is defined as the charge carried by a current of 1 amp in 1 second. Another way to look at this might be that the coulomb is a measure of charge (electrons) and the ampere is a measure of the rate of transfer of those charges.
How much charging ampere required for 200 apmere lead acid battery for ups 12 volt?
To find our what charging ampere to use a simple way is to divide the battery Ampere with its ampere hour (i.e. for car batteries they will say 75ah C/20) this means that the battery has 75 ampere rating based on 20 hour rating... as such to find the charging ampere divide 75 by 20 to get a charging ampere of 3.75... this is for a slow charge - to speed up the charge divide the ampere by 5 hours (to charge the battery from empty to full in 5 hours)...
Where did Andre Marie ampere work?
Andre-Marie Ampere was a French physicist who was one of the scientists who founded the theories of electrodynamics. He lived from 20 January 1775 to 10 June 1836. To honor his contribution, the unit to measure electric current, ampere, was named after him in 1881.
9 amp go in to watts?
Amp(ere) is the unit for current flow. Volt is the unit for electrical tension. Watt is the unit for power Since Watt is Volt x Ampere , there is no way to answer your question. But with your newfound knowledge, you can now calculate yourselves :-)
Define coulomb in terms of ampere?
In SI, the coulomb is a special name given to an ampere second, in much the same way that a watt is a special name for a joule per second.
How you define 1 ampere unit of current?
The official definition is currently that one ampere is "the constant current that will produce an attractive force of 2 × 10-7 newton per metre of length between two straight, parallel conductors of infinite length and negligible circular cross section placed one metre apart in a vacuum". The coulomb (unit of charge) is derived from the ampere. To visualize electrical current, it is more convenient to think of it the other way - the coulomb is a certain number of charged particles (electrons, for example), and 1 ampere is 1 coulomb/second.
How do you measure a boat propeller pitch?
The same way you would measure ANY angle.
Why is 30 milli ampere deadlier than 30 ampere?
What I think atleast. 30 milli ampere is the amount of ampere there's needed to kill a human being, or atleast close to. But you also need a x amount of Voltage. The higher voltage = the lower ampere, and the other way around. But then again it all depends on how much voltage you have. So you can't really say that 30 milli ampere is deadlier than 30 ampere. Because if you have 700 voltage and 30 ampere. Then that will do the same thing to you as 70 voltage and 30 milli ampere would do; most likely kill you. 49 voltage is the amount of voltage there's required to kill a human, with 30 milli ampere. If you have less than 49 voltage, you won't die, it will hurt of course. The reason for this, is that the voltage is what 'carries' the ampere around. The ampere is what strikes, and the voltage is the carrier. Hope this helped a bit.
