Current Per Phase Calculator


In the realm of electrical engineering, the calculation of current per phase is a fundamental task. Whether it’s for designing circuits, analyzing power systems, or troubleshooting electrical issues, having a reliable calculator at hand can streamline the process. In this article, we’ll provide a comprehensive guide on how to use and build a current per phase calculator.

How to Use

Using our calculator is simple. Just input the values for voltage (V) and power (P), and the calculator will automatically compute the current per phase (I) using the formula:

Once you’ve entered the values, click on the “Calculate” button to get the result.


The formula for calculating current per phase (I) is derived from Ohm’s Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance. Mathematically, it can be represented as:


  • I is the current per phase (in Amperes)
  • P is the power (in Watts)
  • V is the voltage (in Volts)

Example Solve

Let’s say we have a system with a power of 1000 Watts and a voltage of 120 Volts. To find the current per phase, we can use the formula:

So, the current per phase in this example would be 8.33 Amperes.


Q: Can this calculator be used for AC and DC circuits?

A: Yes, the formula for calculating current per phase applies to both AC and DC circuits.

Q: What units should I use for entering values?

A: Enter the values for power (P) in Watts and voltage (V) in Volts for accurate results.

Q: Is there any limit to the size of values I can input?

A: No, you can input any reasonable values for power and voltage into the calculator.


Calculating current per phase is essential for various applications in electrical engineering. With our simple yet efficient calculator, you can quickly obtain accurate results, streamlining your workflow and improving productivity.
