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.
AC voltage is varying because it is sinusoidal in nature

No, you cannot accurately measure the output voltage of an Automatic Voltage Regulator (AVR) using a DC meter, as the AVR typically regulates AC voltage for the generator. A DC meter is designed for measuring direct current voltage, while the voltage output from a generator is usually alternating current (AC). To measure the AC voltage effectively, you would need an AC voltmeter or a multimeter set to the AC voltage setting.
You cant.
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.

How do you convert 23 voltage DC to 230 Voltage AC?

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.
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.
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
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.
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.

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.
