## How to convert watts to volts?

### watts to volts calculation formula in case of DC

The voltage V in volts is equal to the power P in watts, divided by the current I in amps:**V(in Volts) = P(in Watts) / I(in Amps)**

**volt = watt(W) / amps(A)**

**V = W / A**

**Let's take an example**

**Example#1**

Calculate the voltage(in volts) where the power(P) is 50 watts,the current flow in the circuit is 5 amps.

V = 50W / 5A = 10V

### watts to volts calculation formula in case of AC single phase

The RMS voltage V in volts is equal to the power P in watts, divided by the power factor PF times the phase current I in amps:**V(in Volts) = P(in Watts) / (Power Factor × I(in Amps) )**

**volts(V) = watts(W) / (PF × amps(A))**

**V = W / (PF × A)**

**Let's take an example**

**Example#2**

Find out the RMS(root mean square) voltage(in volts) where

the power(P) is 300 watts and the PF is 0.8 and the current(I) is 4 amps in the electric circuit.

V = 300W / (0.8 × 4A) = 93.75V

### watts to volts calculation formula in case of AC three phase

The line to line RMS voltage VL-L in volts is equal to the power P in watts, divided by square root of 3 times the power factor PF times the phase current I in amps:**VL-L(in Volts) = P(in Watts) / (1.732 × Power Factor × I(in Amps) )**

**volts(V) = watts(W) / (√3 × PF × amps(A))**

**V = W / (√3 × PF × A)**

**Let's take an example**

**Example#3**

Find out the Root Mean Square voltage(V) where the power(P in watts) is 300 watts,

the PF is 0.8 and the current flow in the circuit is 3 amps?

V = 300W / (1.732 × 0.8 × 3A) = 300W/4.1568=72.17V

If the Current(I)= 2 Amp in the circuit then you can easily do the following conversion(DC)

**10 watts to volts:-10W/2=5V****15 watts to volts:-15W/2=7.5V****45 watts to volts:-45W/2=22.5V****100 watts to volts:-100W/2=50V****1000 watts to volts:-1000W/2=500V****1500 watts to volts:-1500W/2=750V**

For converting watts to volts we must know the current or resistance of the electrical circuit.

We can calculate the voltage without knowing the current or resistance of the circuit. For example,

10 Watts load can be at any voltage level like 1V, 5V, 15V,400V, or any voltage.10 Watts load can have any voltage level.So we can say that 10,15,45,100,1000,1500 watts load can have any voltage level i.e 5V,10V,50V,100V.
