Watt rating is the amount of real power that is absorbed (or supplied). VA is normally the units given to the total complex power which is made up of the real power and reactive power. The formula for complex power is as follows.
S = P + jQ
P is the real power which is used by the resistive elements of the component while the reactive power (imaginary power) is that power which the capacitive and inductive parts of the circuit cause to flow.
Watt ratings are always lower (or equal) to the VA rating due to the fact that it neglects imaginary power that is flowing, because of this both ratings should be taken into account.
What else can I help you with?
Potential difference is measured in a unit called 1 a volt 2 a Watt 3 an Ampere 4 an ohm?
The answer is volt.
What is difference between KVA and MVA?
The volt ampere (V.A) is the unit of measurement of apparent power.Apparent power is the vector sum of a circuit's true power and reactive power.A kV.A (not 'KVA') is the symbol for kilovolt ampere, whereas MV.A (not'MVA') is the symbol for megavolt ampere. So the latter is one-thousand times greater than the former!
How many mega volt ampere are there in a 1 mega watt generator?
In a 1 megawatt (MW) generator, the unit of power is given in terms of megawatts, which represents one million watts. A megavolt-ampere (MVA) is a unit of apparent power equal to one million volt-amperes. Therefore, in a 1 MW generator, the apparent power rating would also be 1 MVA, as the apparent power rating is typically equal to the real power rating in a generator with a power factor of 1.
How source of 6 volt gives 1 ampere current and source of 18 volt gives 0.5 ampere at same resistance is it violation of ohms law?
yes
One volt is equal to?
One volt is the electric potential required to generate one ampere through one ohm. One volt is the electric potential involved when one ampere generates one watt of power. One volt is one joule per coulomb.
What is the difference between ampere and volt?
Liken volt and amp to a water in a pipe. Voltage is the water pressure in the pipe and amperage is the water flow through the pipe. They are two completely different electrical units.
The nec requires that continuous load calculations be increased by an additional percent volt-ampere rating?
25
The unit to measure current is the volt?
The unit of current is the ampere. The unit of potential difference, or electromagnetic force is the volt.
Potential difference is measured in a unit called 1 a volt 2 a Watt 3 an Ampere 4 an ohm?
The answer is volt.
What if your tutor tells you than an ampere and a volt really measure the same thing?
An ampere and a volt do not measure the same thing. Ampere measures electric current flow, while volt measures electrical potential difference or voltage. Having a clear understanding of the difference between these units is essential in understanding electricity.
Can I use 4.5 volt 2 ampere adaptor instead of 5 volt 2 ampere?
yes you can.
Difference between 12volt armature and 24 volt armature?
The main difference between a 12-volt armature and a 24-volt armature is the voltage rating at which they operate. A 12-volt armature is designed to run on a 12-volt electrical system, while a 24-volt armature is designed for a 24-volt electrical system. This difference determines the power and speed capabilities of the armature when used in electrical devices.
What is the unit of measure that expresses potential difference between two electrodes I am battery?
The unit of measure that expresses the potential difference between two electrodes in a battery is the volt (V). One volt is defined as the potential difference that will drive one ampere of current against one ohm of resistance. This measurement indicates the battery's ability to provide electrical energy to a circuit.
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)...
Is The units of electric current is the volt?
NO! (the units of electric current is Amperes).
What is the current carrying of an 1000kVA transformer?
You cannot answer this question without knowing the rated secondary voltage. Once you know this, divided the voltage into the volt ampere rating.
What is is kva?
kVA is kilo-volt-ampere, which is 1000 x volt x ampere. kVA is the unit of apparent power in AC circuits.
