What is watt
It is the power that works, or it produces heat, or in other words, the rate of production or energy consumption. Technically speaking, the rate of a joule of energy in one second is called a watt. You pay the electricity company your cost per unit in terms of the amount of power in a unit of time, typically one hour. For example, if you let the light bulb light up to ten o’clock for a hundred watts, your power consumption of one kilowatt-hour will be enough.
Real power for constant current circuits (for example, a circuit that feeds on a battery) is very simple from the below equation.
P = V x I
But in a circuit that feeds on a sine voltage, such as your home power, the theorem varies, since at any given time voltage doesn’t have a constant value, and naturally, the potential for power will be low and high. But can it not be possible to calculate the average of individual scores for the calculation of the average or the average voltage and, therefore, the average power can be calculated?
The answer is yes. In fact, the 220 volt or 110 volt that you hear for your electricity is the same as the average voltage. (Root mean square or RMS)
What is volt amp
A simpler statement is to calculate consumption amp and consumption watt. Very simply the product of the current flow is obtained in the voltage and for a battery powered circuit, there is essentially no difference between this product and the power per watt.
For the periodic circuit or power supply to the city, the effective value of the effective voltage can be obtained from the product (the same mean values, although the average value is expressed to simplify the understanding of the subject but technically the effective value is better.)
VA = Vrms x Irms
For ohmic loads, there is no intermittent voltage and current in the fuzzy circuit, so there is no difference between the product of the current voltage with that which occurs in practice as power consumption.
