Volts to watts conversion calculator is a common tool for converting physical quantities in many electrical systems. في الوقت الحالي, solar panel system with excellent characteristics, by the industry’s extensive attention and active exploration. For home users, the knowledge of physical quantity conversion is essential to deeply understand and optimize their own solar panel systems.

في هذه المقالة, we will give you a detailed explanation of volts, واتس, and the specific formula for converting volts to watts in DC and AC circuits.

What exactly is a volt (الخامس)?

The volt is a measure of voltage. When used as a voltage unit, the higher the volt value, the higher the voltage in the circuit, the stronger the force of the current; على العكس من ذلك, the smaller the volt value, the lower the voltage in the circuit, and the smaller the force of the current.

From the micro point of view, the volt as a voltage measurement unit, it is used to measure the unit energy difference of a unit electron driven by the electric field force due to the voltage difference. Its value is equal to the work done by the electric field force when the unit positive charge is moved in the circuit, so it is also a unit of potential energy. The electric charge moves in the zero potential energy plane, the electric field force does positive work in motion, the potential energy decreases and the volt value is negative, the electric field force does negative work in motion, the potential energy increases and the volt value is positive.

What is Watt (ث)?

Watt is a unit of power and is one of the most widely used units of electrical physical quantity. It is usually used to describe the amount of energy consumed by an electrical appliance in operation. The more energy consumed to complete a task, the greater the wattage, and conversely, the less energy consumed, the smaller the wattage.

فضلاً عن ذلك, watts can also be used to represent the output power of power generation equipment. In the case of a solar panel system, wattage refers to the power emitted by the solar panel under ideal conditions.

What is the definition of an ampere (أ)?

The ampere is a unit of current, أيّ, in microscopic terms, indicates how much charge passes through a section of a circuit at a given moment, إنه, the magnitude of the rate at which the current passes through a section.

How to volts to watts conversion ?

After understanding the units of the above physical quantities, let’s look at the volts to watts conversion calculator. Since the volt and the watt do not belong to the same physical unit, we need to introduce an intermediate unit, the ampere, for conversion purposes. صيغة التحويل هي كما يلي:

P（w）= V（v）x I（A）

In the above formula, P is the power of the electrical equipment, V is the circuit voltage, and I is the circuit current, namely:Watts = Volts x Amps

In order to better grasp the above conversion formula, taking the household solar system as an example, the household electrical appliances in parallel, the total current of the household circuit is 20A, the power supply voltage is 110v, to ensure the normal supply of household energy, the power of the solar system

P（w）= 20A x 110V = 2200W

Through learning, we have a preliminary understanding of the convert volts to watts. لكن, the above formula only applies to the direct current circuit, the actual application of common AC circuit, we need to use a more complex formula for conversion.

The first thing to know is that AC circuits are divided into single-phase AC and three-phase AC.

single phase alternating current

A single-phase alternating current (تكييف) is a circuit with a single AC voltage in which the current and voltage both change over time at a specific frequency.

For single-phase AC, the formula for conversion volts to watts is:

P（w）= PF × I（A） × V（v）

In the formula, P represents the power of the power system, and V represents the voltage RMS value, إنه, the value of the DC voltage that can produce the same heating effect in the circuit. I represents the current of the circuit, and PF is the power factor of a single-phase AC circuit, إنه, a value used to measure the phase difference between voltage and current in the circuit.

PF is the power factor of a single-phase AC circuit, إنه, it is used to measure the phase difference between voltage and current in the circuit. The greater the phase difference between voltage and current, انخفاض عامل الطاقة, the lower the efficiency of the circuit, and the more unstable the whole system.

three-phase alternating current

Three-phase alternating current (تكييف) is the most commonly used type of alternating current, which consists of three alternating potential with the same frequency, equal potential amplitude and phase difference of 120°.

For three-phase AC, there are two ways to calculate the volts to watts conversion formula.

irst, the RMS voltage is converted to line voltage (V LL) for calculation, and the conversion formula is as follows:

P（w）= √3 × PF × I（A） × V LL（v）

The other is to convert the effective voltage into line voltage (V LN) for calculation, and the conversion formula is:

P（w）= 3 × PF × I（A） × VL -N（v）

The meanings of the symbols in the above two formulas are the same as those in the single-phase AC formula.
