It depends on context. If the potential difference is an electromotive force, then it's symbol is usually E. For all other potential differences (e.g. voltage drops), the symbol is usually either V or U (with the latter symbol used throughout Europe). Symbols for quantities, such as these, are italicised.
With alternating-current circuits, upper case letters (E, V, U) are used to represent peak or r.m.s. values, whereas lower-case letters (e, v, u) are used to represent instantaneous values.

∙ 10y ago'Voltage' means 'potential difference'. So you cannothave a 'voltage difference' which would mean 'potential difference difference'! If you are asking what the symbol for 'voltage' is, then it could be italicised letters E (usually representing the e.m.f. or voltage of a source), or V, or U.

What is used to measure voltage?
a voltmeter is used to measure voltage
Why is a voltmeter used rather than a potentiometer?
A potentiometer is a variable resistor, while a voltmeter is a device that measures voltage.
What is the voltage is used for industrial purposes?
It depends on the country as to which voltage is used for industrial purposes. In the US, for welding for example, voltage may be 480 volts. The frequency in the US is 60 Hertz.
What is used to increase or decrease voltage that enters a house?
A transformer can be used, either a step-up or step-down transformer, to deliver the power at a different voltage from the normal supply voltage.
What units are used for v?
voltage
What is the Symbol used for AC voltage?
a sine wave (~)
What does the symbol u mean in physics?
The symbol 'u' is often used in place of the prefix 'micro-' in math and physics.AnswerThe symbol U is used to represent voltage. In this context, a lower-case 'u' represents an instantaneous AC voltage. In thermodynamics, it is used to represent internal energy.
What is an amp symbol?
The symbol used for amperage in formulas is the letter "I", for voltage "E" for watts "W". The formula for watts is W = I x E.CommentThe symbol for electric current is I; the symbol for ampere is A. The symbol for voltage is E, V, or U, depending upon context, and the symbol for volt is V. The symbol for power is P, and the symbol for watt is W.
What is the symbol used in formulas to represent voltage?
The symbol is actually a letter. The original letter was an E which stood for Electromotive force. Now-days the E is substituted by the letter V which of course stands for voltage.
What is a symbol of a voltage?
V
What does the symbol V stands for in electricity?
The symbol V stands for voltage.
What is symbol for volts?
The symbol for electrical volts is "V". <<>> The symbol for voltage is the letter E. It stands for Electromotive force known as EMF.
What is that symbol that looks like a horseshoe in physics?
In physics, what is the symbol that looks like a horseshoe, and relation to voltage
Where can you find a high voltage symbol?
rail way gates
What is the basic difference between the symbol E and V in electrical and electronics?
E = Voltage drop V = Voltage
How much voltage is used per day?
Voltage is not "used" Voltage is constant.
What is the symbol for dc voltage?
The most common symbol used for DC voltage is two, short, parallel horizontal lines, only the bottom one is dashed. Click here for an image: http://upload.wikimedia.org/wikipedia/commons/9/9f/Direct_current_symbol.svgAnswerThe ISO recommends lower case letters as follows: d.c., except where it is used at the start of a sentence, where it should be capitalised: D.C. For example:"A voltage of 12 V d.c.""D.C. voltages are supplied by batteries."
