Are 250 voltage reading considered to be nominal 240 volts?
Different countries have different legal limits to how much their electricity supply voltages may vary. In the UK, for example, the nominal supply voltage for residential supplies is 230 V, but this is allowed to vary between -6% and +10%. So, as you can see, and 'actual' voltage of 250 V is within the allowable upper limit (253 V) for the nominal voltage of 230 V. So, to answer your question, you need to check what the allowable variation is at your location (your electricity supplier can confirm this) -I would guess that 250 V would be well within the allowance for 240 V.

The word nominal means the lowest possible safe amount. So, nominal current or nominal voltage is the lowest amount necessary to perform an electrical function like keepin…g a light turned on. Answer The original answer is incorrect. 'Nominal' simply means 'named'. So a 'nominal voltage' is the 'named voltage', as opposed to an 'actual voltage'. For example, the nominal voltage of residential supplies in the UK is 230 V; however, this value is allowed to vary between +10/-6% of the nominal voltage. In other words, a nominal voltage of 230 V may vary between 216 V and 253 V.
120 volt to ground---208 across 2 lines
It is the rated voltage of an electric equipment. It is the voltage at which the device is designed to operate. Another Answer Nominal means 'named'. So a nominal voltage is …the 'named' voltage. For example, the nominal voltage of the supply system in Britain is 230 V. But its actual value is allowed to vary between 216.2 V and 253.0 V.
Yes if the bulb is an incandescent type of bulb. Further InformationThe voltage printed on a lamp is its nominal, or named, value. For example, the nominal voltage of …the UK's supply (since January 1995) is 230 V. But this does not mean that the actual voltage is necessarily 230 V, as it does vary. In fact, it is allowed to vary from -6% to +10% of its nominal value -in other words, from 216.2 - 253.0 V. So, as you can see, it would be considered quite normal for a 240-V lamp to be subjected to 250 V.
I have my 120 volt appliance and in Philippines we have 240 volt. Can a 110 - 250 volt adapter be used?
An adapter can be used. Make sure that the adapter that you use is of a capacity that it can produce the amperage that your appliance needs. An adapter too small will burn its…elf open and will be of no use to anyone. Remember; Watts = Amps x Volts.
Why on a certain 460 volts one leg to ground shows no voltage but when you have a reading on each phase 230 volts?
My first thought is this is probably a corner grounded delta system, but I'm confused by your voltages. If this was a 460v (L-L voltage) ungrounded or corner grounded system, …the phase to ground voltage is meaningless, but the phase to phas voltage will be 460v all around the delta. If you have a 460v system and you're only seeing 230v, there's something wrong.
First it would depend upon the type and voltage rating of the battery. If it is a lead acid battery, I would recommend charging it to its recommended voltage and load testing …it. A fully charged 12 volt automobile battery should read 12.6 volts. A battery that reads 10.5 volts is completely drained. If the battery is fully charged and only read 10.5 volts it needs to be replaced.
To get the actual household voltage range figures for your locality it is best to ask a local licensed electrician or your local electricity supply company. As long as yo…ur appliance has a rating plate, user guide - or has similar information printed on its body - which says it was designed to run on a range of voltages from 120 to 240 volts ac, you can plug it in. In the US, Canada and other countries which use a similar 60 Hz alternating current system, circuits for lighting and low-power appliances run at 120 volts plus or minus 10%, in which case the voltage range could be from 108 Volts to 132 Volts. In countries in Europe and other world areas which use 230 volts 50 Hz alternating current system, circuits for lighting and low-power appliances now run at 230 volts plus 10% or minus 6%. Thus the mains supply voltage will remain within standards even if it varies between an upper limit of 253 volts and a lower limit of 216.2 volts.
If a single phase 240 Volt ac is applied to a full wave bridge rectifier. what will be the resultant dc voltage?
A: the rms value will be169 volts add a capacitor and no load 240 volts and the average will be 153 volts
Yes, it comes in the form of a transformer. Small transformers are available to power small appliances which draw only small currents. These are mostly consumer devices such… as electric shavers; mp3 music players; battery chargers for cellphones, cameras, etc. But if you are asking how to operate a large appliance (such as a washing machine or dryer) that needs 240 volt on only 120 volts, it cannot be done. Why? Because of the very good reason that the appliance was built to run on a 240 volts service and 120 volts is only half that voltage - much too low! More technical details If they are appliances that have to use a lot of power, like clothes dryers, kitchen ranges, etc., the answer to this question has to be No. Apart from International voltage issues, there are good technical reasons why some things made for the US, Canada, or other countries using similar mains supplies, are designed to run on 220 to 240 Volts instead of 110 to 120 volts. The main reason is how much current is needed to get the required amount of power into such appliances that have to use a lot, like clothes dryers, kitchen ranges, etc., because if you double the voltage you only need to supply half the current (Amps) to produce the same amount of power. (Watts or kiloWatts.) If you tried to use something that was designed for 240 volts on only 120 volts, the result is not that you would get half the power output: you would get only a quarter!

Your volt meter reads 16 volts at the battery at idle The alternator and voltage regulator have been replaced Do you have a problem?
Alternator Output Voltage Range Generally, alternator output voltage is consider OK if it is in the range between 12 1/2 volts to a maximum of 16 volts. Therefore, althoug…h the output is at the maximum, you do not seem to have a problem. Usually, if the battery has had a lot of drain, then the alternator output will run at the maximum until the battery is fully charged.
A circuit has a voltage of 240 volts and an inductive reactance of 30 ohms what is the current flow?
A circuit with a voltage of 240 volts and an inductive reactance of 30 ohms would have a current of 8 amperes. Reactance works just like resistance. The difference is …that the phase angle between voltage and current is not zero, so the ratio of true power versus apparent power is not one. Phase angle and power factor depend on frequency. This was not specified in the question, so it is not answered.
Why does the voltage on every other breaker in your box read 104 volts while the other breakers read 124 volts?
You may not have a good connection one your "neutral" wire, somewhere between the breaker panel and the transformer. Note that the neutral wire is the center of the 240 V fe…ed, and if the connection is inadequate, dirty, oxidized... you may experience some neutral "float". Make certain that the center feed of the breaker panel is tightened, and beyond that, there isn't much that YOU can do; you'll need to contact the local electric service provider. Just a warning here... if you haven't worked with live circuits before and REALLY know what you're doing, make certain that you shut off the power at the meter base before you attempt to do anything to the inside of the breaker panel. An open breaker panel exposes you and anyone else nearby to a very real and deadly potential for electrocution.
For lead-acid chemistry, as in a car battery, think 13.6 volts DC.
Answer for USA, Canada and countries running a 60 Hz supply service. Yes, the voltage ratings on electrical equipment are the responsibility of the manufacturer. The manufac…turer uses the highest end of the scale so that it encompasses the the highest variation in voltage in that voltage category. Usually you will see equipment with the ratings stated at 130/250 volts. This means that any voltage up to and including the stipulated voltage rating can be used to connect to their equipment.
