V
The symbol V stands for voltage.
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.

The symbol for electrical volts is "V". <<>> The symbol for voltage is the letter E. It stands for Electromotive force known as EMF.

E = Voltage drop V = 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.
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.
Voltage = Current x Resistance is often written V = I x R. Ohm's Law is: E = IR E is voltage
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.
lack of charging system voltage.
The force that makes electrons move is a voltage, or potential difference and both are measured in Volts. When electrons move, the rate of movement is current, measured in Amps. The amount of current is dependant on both the resistance in a circuit and the voltage. The higher the resistance, the lower the current. The higher the voltage, the greater the current. The symbol for voltage is "V" and confusingly, the symbol for current is "I". The unit of resistance is the Ohm with the symbol "R" or the Greek symbol for omega.
