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.

Why is it not good to operate a transformer above its nominal voltage?

Overexcited Transformer.  Operation above the rated supply voltage causes the ferromagnetic core to enter saturation; this means that the primary inductance is reduced and s

What is nominal voltage?

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

What is the difference between voltage and current?

Voltage . . . the difference in electrical 'pressure' between two points, that makes electrons want to move from the higher-pressure point to the lower-pressure point if th

What is difference between voltage and current?

Voltage . . . the 'pressure' between two points that makes electrons 'want' to move from one of the points to the other one. More pressure is called more 'volts'. Curren

What is the different between voltage and current?

current is nothing but flow of electic charges through a particular area.it is denoted by I.its unit is ampere. V=IR by ohms law. voltage Voltage is the potential energy t

What is the difference between current and voltage?

Voltage is the cause and current is its effect. Voltage is the potential difference between two points. When charges flow due to this potential difference, we say that current

What is the differences between current and voltage?

Think of voltage as a potential. A bunch of free electrons looking for someplace to go. The current is how they get there. If you think of a vat of water being a voltage and d

What is the difference between EMF and voltage?

E.M.F: Is the potential difference between two terminals when there is no current i.e. circuit is open, therefore [EMF = OCV]. OCV :open circuit voltage. Voltage: Is the po

What is the difference between voltage and amperage?

Voltage is the "pressure" of electricity, whereas amperage (current) is the "flow" of electricity. Voltage can be present without amperage (at a switch in the off position), b

Difference between voltage and emf?

'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or

What is difference between nominal and terminal voltage?

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 manufactur

What is the difference between voltage and signals?

  That's a pretty good question.   In computers a change in voltage level is usually the data signal. There are many industrial applications where a change in current i

The question and answer are locked and cannot be edited.

What is the difference between energy and voltage?

  Answer     Voltage is (potential energy).   Answer     Energy is the amount of work that the electrical current can perform... total watts. Voltage

What is the difference between voltage and watts?

Voltage is electrical pressureWatts is power, the product of voltage and amperage   Answer 'Voltage' is another word for 'potential difference', which is measured in volts
