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 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 does the letter E stand for in the Ohm's law formula?

Correct Answer= In the Ohm's law formula, the letter "E" stands for voltage(volt)AnswerThe symbol, E, together with the symbols V and U, is used to represent potential difference. Specifically, E is used to represent electromotive force or an open-circuit voltage, whereas V and U are used to represent potential differences in general.

What Symbol is used for voltage?

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.
