Alternating current (AC) is a type of electric current, in which the direction of electron flow comes and goes at regular intervals or in cycles. The current that flows through power lines and the electricity normally available in homes from wall sockets is alternating current.

The ratio of the output power from the UPS to the imput power from the AC utility line mode

The ampere-hour (Ah symbol) expresses how much energy can circulate through a certain circuit during one hour. It is used to measure the capacity of electric batteries

Unit of measurement that helps us to know the amount of electric current that passes through a conductor, it is very useful to determine the size or caliber of the conductors, whether in an electrical installation, in a transformer, etc. the greater the amount of current, the greater the necessary diameter of the electrical conductor.

The term Amp is a unit of the International system that reflects the intensity of the electric current.

The alternating electric current expressed in amperes, like the alternating voltage, forms a sinusoid, therefore, to measure it more accurately, several samples are required, an ammeter that performs this operation with more samples and a better calculation of the average will give better quality. For measurement, it is convenient to know that the alternating electric current when seen in its waveform by means of an oscilloscope will see that it deforms more easily than the voltage and therefore, we require better instruments to measure it.

The electric power furnished by an electric power plant.

The average value of any electrical signal is obtained by taking the total area under the curve of a cycle and dividing by its period. The area above the x-axis is considered positive and the area below the same axis is considered negative. These signals can be voltage or current.

A voltage regulator is an electrical device designed to supply a stable voltage and to protect electronic and electrical equipment connected to a power line against phenomena such as power surges, voltage sags, and voltage fluctuations. A voltage regulator can receive a variable input voltage and automatically provides an appropriate output voltage for the correct operation of the equipment connected to its output.

It is an alternating current waveform that varies in magnitude as a function of time and oscillates above and below a defined reference level.
