v
To control the amout of voltage to the processor
The letter E
It depends on what language you are talking about. In English, the letter X is least used for first names.
many used for law and biz
Letter Of Inquiry
If the wave is sinusoidal, the equation to determine voltage as a function of phase angle, is: V = V(p)sin(theta) where "V(p)" is peak voltage and "theta" is the phase angle. In the time domain, the equation for voltage is V = V(p)sin(wt) where 'w' was used for the Greek letter omega, which stands for frequency in radians per second and t is elapsed time from zero volts in seconds.
Variable
Power (Joules) = the square root of the voltage squared divided by the resistance
a variable
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.
There is not a specific word that is used to bold a number in a math equation. Generally, a number or letter is not bold in a math equation, if a letter is of significance, it is normally capitalized.
It can be any letter of any alphabet: Roman, Greek.
Ohm's Law relates Voltage, Current, and Resistance. The equation is Voltage = Current times Resistance. Knowing any two, you can figure out the third, and that is one of the principles of basic circuit analysis.
It is called a variable. x is the most used variable.
Voltage is not "used" Voltage is constant.
a voltmeter is used to measure voltage
They are very important in many areas such as maths and physics. They are used to work out unknown's. For example in physics if you know the current through a circuit, and the total resistance, and you need to find out the voltage, you can use the equation: Voltage= current * resistance, to work out.
