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.
Nominal voltage is the 'named' voltage -for example, the nominal supply voltage in the UK is 230 V. But this is not necessarily the actual voltage at a particular time. A nominal voltage is normally expressed together with the percentage by which it is permitted to vary from that stated value. For example, in the UK, the nominal voltage is expressed as: 230 V +10% / -6% --in other words it is allowed to vary between 216.2 and 253 V.The term, operating voltage, isn't actually defined anywhere, but is usually taken to mean the actual voltage supplied to a device at any particular instant, and this should always fall within the allowable range of the supply system's specified nominal voltage. The operating voltage can be found simply by measuring it with a voltmeter.
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 keeping a light turned on.AnswerThe 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.
'Nominal' means 'named'. So a 'nominal' voltage is the named voltage of a system. For example, when we talk about a 120-V or 240-V system, we are describing their nominal values, not their actual values which can change from moment to moment.
A zener diode has a voltage when it reachesbreak over it may be 5v 12vor other voltage as manufactured. The manufacture will produce a 5v zener or is it? This voltage can change from device to device but the mean or nominal voltage will be as close as 5v as possible. So when buying a 5v zener do not expect 5v absolute but a nominal 5 v ZENERS are designed for a specific voltage [ THEREFORE NOMINAL] as mentioned above . depends on the voltage required it can be bought within a specific voltage -/+ a % of the breakdown
The rated voltage of a motor listed on the nameplate is called the terminal voltage. This indicates the actual voltage on the motors terminals at which at which the manufacturer designed to operate. Whereas, Nominal voltage is the design or configuration voltage of the electricity distribution system.

It can be used for anything with a nominal 12 v requirement. In cars everything runs on a nominal voltage of 12 v but is designed to run on 13.8 v which is the voltage when the car is running.
The standard nominal voltage in Canada for a single-phase residential supply is 240/120-V split-phase supply.

Power supply voltages vary with the amount of load placed on them. In many countries the supply voltage has a nominal voltage and a plus or minus tolerance. In the UK the nominal voltage is 230 v but the allowable variation is -6% +10%, in other words 216-253. At my house the voltage is usually between about 236 and 253 volts.
.230kvAnswerThe nominal supply voltage to a residence depends on the national electrical standards in the country in which you live, but no residential single-phase supply exist in the kilovolt range. European countries have a standard nominal voltage of 230 V (which you could express as 0.230 kV, if you really wanted to!) and the US and Canada have a nominal 240/120 V supply voltage.And the correct symbol for kilovolts is 'kV', not'kv'.
230 V is the standard nominal voltage in the UK. 'Nominal' means the 'stated' voltage, but this is allowed to vary, under government legislation, between +10% and -6%, which means it is allowed to drop to 216 V.The motor's rated voltage of 208 V is also a nominal voltage, but is not a standard UK nominal voltage so, without knowing what in which country the motor is manufactured, we'll assume that it is allowed to vary between, say, +5% to -5%. This means that it can operate at voltages up to 218 V. If it's allowed to vary between, say, +10% and -10%, then it can be operated up to 229 V.So there is an overlap between the nominal voltage of the supply and the rated nominal voltage of the motor so, in all likelihood, the motor should be able to run with a 230-V supply. On the other hand, there will be times when the supply voltage will exceed the upper limit of the motor's nominal voltage, and this may -over time- lead to a breakdown in its insulation and its ultimate failure.
It depends on where you live, as most countries have their own standards. In the UK, for example, the nominal (named) mains voltage is 230 V, but it is allowed to vary between +10% and -6%. The nominal frequency of this voltage is 50 Hz, and this is allowed to vary between +/-1%. In North America, the standard nominal supply voltage is 120 V at 60 Hz.
Short answerHouse in US = 156V peakHouse in Europe = 325V peakLong AnswerAC voltages are usually identified by their RMS voltage. This is a mathematical calculation of the "average" or DC equivalent voltage. It is smaller than the peak voltage by a factor of about 0.707 for a sine wave AC which is the normal type.The actual peak voltage in your house depends on a number of factors. The most important being what the nominal supply voltage is in your area.The US typically uses a nominal voltage of 110V RMS = 156V peakMost of Europe uses a nominal voltage of 230V RMS = 325V peakActual voltages in a particular house can vary significantly from nominal. Some specifications call for +/-10% from nominal. The difference is caused by voltage drops at various stages in electricity transmission. There can also be variations due to shortages of supply, etc.
The answer to this question depends entirely on where you live. All voltages quoted are 'nominal', or 'named', voltages and not the actual voltage as you would measure it with a voltmeter. National regulations stipulate how much these nominal voltages may vary.For example, in the UK, the nominal voltage is 230 V, and the allowable variation is between -6% and +10%. So, the maximum (actual) allowable voltage is 253 V.In some residences, e.g. Cyprus, a three-phase supply is common for residences, in which case the maximum nominal line-voltage is 400 V, with a nominal phase-voltageis 230 V.
The nominal voltage of a Duracell DL123 battery is 3 (lithium) nominal volts or 3.6 (Li-ion) nominal volts.
'Nominal' means 'named'. So a 'nominal' voltage is the named voltage of a system. For example, when we talk about a 120-V or 240-V system, we are describing their nominal values, not their actual values which can change from moment to moment.
