Watts to Volts Canculator 

Before we delve into the conversion process, let's gain a clear understanding of what watts and volts represent in the world of electricity.

Watts (W): Watts are the units used to measure power. In essence, they quantify the rate at which energy is transferred or consumed in an electrical circuit. The concept of watts was introduced by James Watt, a Scottish inventor and engineer, in the 18th century. Watts play a pivotal role in determining the energy efficiency and capacity of electrical devices.

Volts (V): Volts, on the other hand, measure electrical potential or voltage. They signify the force that drives electric current through a circuit. The term "volt" was named after Alessandro Volta, an Italian physicist known for his contributions to early battery development. Volts are essential in understanding the electric potential difference across components and systems.

DC Watts to Volts Calculation

In direct current (DC) circuits, the conversion from watts to volts is straightforward:

V(V) = P(W) / I(A)

Here, V represents voltage in volts (V), P is power in watts (W), and I stands for current in amps (A). This equation is instrumental in determining the voltage when power and current values are known.

AC Single Phase Watts to Volts Calculation

When dealing with alternating current (AC) in single-phase circuits, the relationship between watts and volts involves the power factor (PF):

V(V) = P(W) / (PF × I(A))

Understanding the power factor is crucial in accurately calculating voltage in single-phase AC systems.

AC Three Phase Watts to Volts Calculation

In three-phase AC circuits, two methods are commonly used to calculate voltage:

Line-to-Line Voltage (VL-L): The formula for determining voltage in this scenario is a bit more complex:

VL-L(V) = P(W) / (√3 × PF × I(A))

It considers the square root of 3, power factor (PF), and phase current (I) to calculate line-to-line voltage.

Line-to-Neutral Voltage (VL-N): This calculation is more straightforward:

VL-N(V) = P(W) / (3 × PF × I(A))

When line-to-neutral voltage measurements are available, this equation provides the voltage in three-phase systems.
