What is diffence between ac volt?

Answer 1

AC is short for alternating current and DC is short for direct current.

In the case of an AC signal the current is going backward and forwards at the rated frequency of the signal (so 240V at 50Hz would mean the terminals vary between 240V and -240V and back again 50 times a second). If you were electrocuted by AC you would be repelled away from it.

In the case of a DC signal the current is in one direction and the voltage will remain either positive or negative (so a 240V signal would stay at 240V and the current would flow positive to negative - conventional current). If you were electrocuted by DC you would stick to it and probably suffer some serious burns, which is one reason for high voltage electrical supplys being AC.

I hope that answers your question!

Answer 2

In general, we always measure alternating current quantities in root-mean-square (rms) values. The rms value of a sinusoidal waveform is 0.707 times its amplitude, or peak value.

The rms value of an alternating-current is exactly equivalent to the value of a direct-current that does the same amount of work. Since voltage is proportional to current, the rms value of an alternating voltage is exactly equivalent to the corresponding value direct voltage.

So, 230 V ac is exactly equivalent to 230 V dc -they will both produce exactly the same amount of energy in a given load.

The most obvious answer to the question is that AC is 'Alternating Current'. That is current that changes voltage regularly, in the form of a sinusoidal waveform. In the UK it changes at 50 cycles a second and 60 in the USA. AC normally comes from a generator known as an alternator.

DC has a constant voltage and is normally supplied by batteries.

Answer 3

AC voltage refers to alternating current voltage, which changes direction periodically. This type of voltage is commonly used in household electrical outlets. On the other hand, DC voltage stands for direct current voltage, which flows in only one direction. This type of voltage is often used in batteries and electronic devices that require a constant power source.
