Watts (w), volts (V), and amperes (A) are the basic units of measurement commonly used in electrical system calculations. In order to convert between the three, we need to recognize the specific measurements of the following units.
Watt is the unit of measurement of electrical power, is the most widely used unit of electrical physical quantities, usually used to describe a certain kind of electrical appliances to complete a certain job is to consume the amount of energy. The more energy it takes to do the job, the greater the wattage, and conversely, the less energy it takes to do the job, the smaller the wattage.
The volt is a unit of potential energy, often used to describe the “force” of an electric current passing through a circuit. From a microscopic point of view, it is a measure of a unit of electrons in the electric field due to different TV produced by the energy difference between the number of units, the size of its value is equal to a unit of positive charge due to the action of the electric field force from one end of the circuit to move to the other end of the amount of work to be done.
The greater the value of the volt, the greater the force of the current in the circuit, and conversely, the smaller the value of the volt, the less the force of the current in the circuit.
An ampere is a unit used to measure the magnitude of an electric current. From a microscopic point of view, it indicates how much charge passes through a certain section of a circuit in an instant, i.e., the magnitude of the speed of the current through a certain section.
After learning the basics above, you can next realize the conversion between watts, volts, and amperes by calculating the following.
