Why was the mains votage changed from 240 volts to 230 volts a few years ago?

This probably refers to the UK which used 240 v until the UK joined the European Community. Europe has always used 230 v so the solution adopted was to redefine the UK supply as 230 v, but no actual changes were made to the supply except to widen the allowed range of voltages. In the UK the nominal voltage range is 230 v -6% +10%, a range of 216.2 to 253 volts, which accomodates the almost universal 240 v supply in the UK. In practice the only appliances that are highly sensitive to voltage are incandescent bulbs (including halogen), and these are marked 240 v.


Can you plug a 220V appliance into a 230V outlet?

Assuming United States: 110=115=120 volts 220=230=240 volts The numbers have changed over the years, but now services are typically 120v or 240v. Anything listed for 10 volts one way or the other is designed for those voltages.


What is the voltage of a john Deere lawn tractor battery?

If it is a model from the last fifty years it is a 12 volts battery.


Why battery voltage is maintained at 12V?

It has become the standard and has been so for over 50 years. It was 6 volts in up until the late 50s.


Can you plug in a 115 amp welder into a 110 volt outlet?

yes. 110,115,120,125 and even 130 volts are all in the same catagory. as power companies increased their output voltages through the years, 110 became 115, then 120, and so on. when buying light bulbs, look for the 130 volts on the bulbs data. not wattage, voltage. they will last far longer than 115,120 volts


What is the charging system output on a 2000 Harley Davidson Electra Glide?

It can't be more than about 15 amps. I have had my bike for 8 years and it has always dropped down to about 10.5 - 11 volts on the voltmeter at idle which isn't right. The voltage at the battery is more like 12.2 volts at idle. When you rev it up, the voltage eventually gets up to about 14 volts. I have replaced both the battery and the regulator. I think the stock alternator is too small for the load.


What are the best LED replacement bulbs?

It really depends on where you are going to use the bulbs!All the light bulbs do not operate the same voltage for starters, there would be nothing surprising about that, but unless you are aware of the differences between them you could be in a little shock. LED bulbs come in two primary voltages: mains voltage and low voltage.Mains Voltage BulbsThe mains electricity supply in the United Kingdom is 230 V Ac (Alternating Current). This is used to supply the majority of domestic and commercial lighting.LED (Light Emitting Diodes) operate at low voltage DC (Direct Current). As such, LED bulbs that are designed to run straight off the mains, like GU10, B22 or E27, require a driver to change the voltage from 230 AC.You will observe about GU10 LED bulbs (230 V) is that they are slightly longer than the low voltage MR16 bulbs(12 V). This is due to the fact that the driver unit is placed into the GU10 fitting.Low Voltage BulbsLow voltage bulbs, are simply lights that run at a lower voltage than provided by the mains electricity supply. They used to exist in the cars where connecting to the mains electricity supply was not viable and the lights would have to run off either a 12V or 24V engine battery instead.Low voltage lighting in houses is a recent innovation. It is created primarily for fittings in kitchens and bathrooms. Instead of being connected directly to the mains supply, an intervening transformer 'steps down' the mains voltage.When you exchange your old halogen bulbs for MR16 LED, there is no guarantee that they will work with your existing 12 V transformer. Contact your retailer to determine whether or not you need to upgrade your system.LED lights have come a long way in the last few years and so have the prices so keep looking. Any good LED lighting website will have info on which lights are best for the application you need them for so have a look around.


What voltage setting should be used when charging a motorcycle battery?

12 volts is the standard and has been for many years. In the past, some motorcycles and especially scooters and small bikes had 6 volt batteries.


What voltage of electricity is in a plug?

Assuming that you mean a mains plug, then the voltage across the live and the neutral pins depends entirely on the the supply coming in to the socket. North America is rated at 110V while in Europe, the standard voltage is 230V. All supply comanies are allowed a tolerance of a few percent either higher or lower than the rated voltage. However, on a project I worked on in Eastern Europe some years ago, I monitored the voltage and although it was supposed to be 220V in that particular country, what I saw was between 156V and 250V. So, even if you know what the voltage, should be, you can never rally be sure!


Will touching a 220 volt wire cause cardiac arrest?

Not necessarily, I have been electricuted at 240 volts at 11 years old and did not suffer Cardiac Arrest. I have seen workers being hit at 50,000 volts and not suffer CA, but received major burns and hospitalization and out of work for 3 months. It's the current not the voltage that kills you. 10 milliamperes or .1amp can.
