What is the mains voltage supply in the UK?
0.8-1.2V Depends on manufacturer and technology options.
Since 1995 230v 50Hz
At Least, 115 volts. Which is standard from a wall outlet. If should not matter how many volts your computer needs, but the watts does. For most computers they need anywhere f…rom 100-800 watts.
In order to transmit electricity efficiently, high voltages are used. This high-voltage electricity is then converted to low-voltage electricity at electricity substations… (transformers). I'm not sure whether you want to know the transmission voltage or the voltage that comes out of wall sockets. Transmission voltage The national grid in the UK runs on mainly 400kV AC system with an HVDC system, that runs on 400kV too, across the English Channel. Other voltages in use are 275 kV and 132kV although these are not really classified as transmission voltages. End-user voltage If you use electricity in the UK, the nominal voltage at the wall socket is 230V. (This is the RMS voltage, which means if you are running something like a lightbulb, heater or kettle it's equivalent to 230V DC. The peak voltage is this multiplied by the square root of 2.) Additional Answer UK transmission voltages are 400 kV and 275 kV; distribution voltages are 132 kV, 66 kV, 33 kV, and 11 kV.
The UK voltage is now 230 V +10% /- 6%, AC, 50 Hz. However, it's worth noting that this 'new' nominal voltage has been nothing more than a 'paper exercise' to comply with Eur…opean harmonisation standards. In practice, nothing has been done to change it from the original UK standard, which was 240 V +/- 6%. (If you compare the allowable percentage variation for each standard, you will note that the range of allowable voltages is roughly the same!)
The supply voltage of the 8085 is 5 volts.
The power supply in a PC is a complex device using switch mode circuitry and transformers to generate +and- 12v, for modems and communications ports. +and-5volts for the… logic circuitry,3volts for the processor. All these supplies are generated and electronically regulated. It is such a waste when they are thrown a way still working. They are mini masterpieces of electronic engineering and are capable of starting a car!
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.
The term, 'nominal', simply means 'named'. For example, the nominal supply voltage for a residence in the UK is 230 V. But this doesn't mean that the actual supply voltage is …230 V, because the supply voltage is allowed to vary by -6% and +10% of the nominal voltage. In other words, the actual voltage could be anywhere within the range of 216.2 V to 253 V. In fact, during periods of heavy load, the actual voltage would tend towards the lower end of this range, whereas during periods of higher load, the actual voltage would vary towards the upper end.
The maximum supply voltage per the data sheet is 5.25 volts. This is a common max for TTL type IC's.
The usual voltages produced by the power supply in a standard personal computer system are 5 volts and 12 volts. For more information see the Related Link shown below.
110v and 240 v
A: Depends on the circuitry involved an op amp normally has a 90 Db rejection from variation, Logic gates however are more sensitive to power supply variation for the simple p…oint that triggering points changes which translate in false triggering and the circuits miss behaving
These days, in order to comply with EU requirements, the nominal ('named') voltage in the UK is 230 V (rather than 240 V) and it is allowed to vary between -6% and +10%. The …reason for this voltage is that is the standard used in the UK, and it has the advantage of enabling appliances rated up to approximately 3 kW to be connected whereas, in North America, the 120-V system will only support appliances up to approximately 1800 W.
