Negative voltage is voltage that is more negative in polarity than the ground of the circuit.
AnswerSince 'voltage' is simply another word for 'potential difference', it can be neither negative or positive in the 'charge' sense! These terms can only be applied to 'potential', not to 'potential difference' (voltage).
So, the terms 'positive' and 'negative', when applied to voltage, simply indicate sense or direction in which the potential difference is acting. For example, if you decide that a car battery's voltage is acting in the 'positive' sense in the charging circuit, then the alternator's voltage must then be acting in the 'negative' sense -in other words in the opposite direction to the battery.

"Negative voltage" is essentially a meaningless term, since potentials can only be defined relative to other potentials. "Negative voltage" is basically the same as saying "I hooked the battery up backwards" ... depending on the exact components of the circuit, it may work precisely the same way or it may not work at all.

When was Voltage AC created?
Voltage AC was created on 2004-12-14.
Why ac voltage varying?
AC voltage is varying because it is sinusoidal in nature
Who to increase torque of ac motors?
ac voltage
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
Can you connect an AC source in series to DC source - then what happens to the current under a steady state condition?
With an AC and a DC voltage source in series, the DC voltage can be added to the RMS value of the AC voltage to give the effective voltage.
You are wiring a LED lamp through a transformer you have a polarized plug and you know positive and negative The transformer is marked live and neutral Does live correspond with positive or negative?
LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.
The change from negative to positive and from positive to negative in an alternating current?
Is called AC voltage or current.
ABS sensor produce AC voltage or DC voltage?
AC !
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
When was Voltage AC created?

Why ac voltage varying?
AC voltage is varying because it is sinusoidal in nature
What is the voltage for a printer?
Most of the printers offered in the USA have a voltage of 110V AC input and 8V AC output, whereas the printers offered in the Europe have input voltage of 220V AC and output voltage of 8V AC.
Can you say which bridge rectifier voltage has the highest out put voltage?
A: NO the power output will be higher. Bridge rectifiers do not provide more voltage output it just add more power by rectifying both positive and negative voltage of the AC input
Why AC waveform positive and negative voltage value compared to DC that had only positive value of the voltage?
because of the type of generator used in making ac voltage: it makes Ac which is harder to manage, but the generator is really simple. Ac switches the positive and negative, or ground polarities and the length of time it is on one polarity is determined by it's wavelength. There are also different types of waves. Sinular waves are... well,.. wavy they gradually switch polarities by slowly decreasing voltage until it is zero, then rising in voltage of the other polarity. then, there are box waves which switch directly from one polarity to another. And, your grammer isn't the best.
Is tranformer used to increase or decrease AC voltage?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.
How does capacitor discharge while ac supply is on?
For part of the AC voltage wave, the capacitor will be above the source voltage, and will discharge until the AC voltage wave increases above the capacitor's stored voltage.
What is the diffemrence between ac and DC?
If you take instantaneous measurements of an AC voltage you will see it vary from a plus value to a minus value. In typical power applications it is a waveform that looks like a sine wave. Google "sine wave" to see a picture. The frequency for U.S.A. AC is 60 Hz. This means that 60 times a second the voltage will start at zero transition to a maximum positive voltage then go back to zero and to a maximum negative voltage and then back to zero. DC is a constant voltage no matter when you measure. It is simply a straight line when compared to an oscillating AC voltage waveform.
