Current per Phase Solution

Follow our step by step solution on how to calculate Current per Phase?

FIRST Step Consider the formula

I ph = \frac{S \cdot 1000}{E ph \cdot 3}

Next Step Substitute values of Variables

∴

I ph = \frac{48kVA \cdot 1000}{800kV \cdot 3}

Next Step Convert Units

∴

I ph = \frac{48000W \cdot 1000}{800000V \cdot 3}

Next Step Prepare to Evaluate

∴

I ph = \frac{48000 \cdot 1000}{800000 \cdot 3}

LAST Step Evaluate

∴

I ph = 20A

How to Evaluate Current per Phase?

Current per Phase evaluator uses Current per Phase = (Apparent Power*1000)/(Induced Emf per Phase*3) to evaluate the Current per Phase, The Current per phase the formula divides the apparent power by the product of the induced EMF per phase and the number of phases. The multiplication by 1000 is used to convert the apparent power from kilovolt-amperes (kVA) to volt-amperes (VA). Current per Phase is denoted by I_ph symbol.

How to evaluate Current per Phase using this online evaluator? To use this online evaluator for Current per Phase, enter Apparent Power (S) & Induced Emf per Phase (E_ph) and hit the calculate button.

FAQs on Current per Phase

What is the formula to find Current per Phase?

The formula of Current per Phase is expressed as Current per Phase = (Apparent Power*1000)/(Induced Emf per Phase*3). Here is an example- 20 = (48000*1000)/(800000*3).

How to calculate Current per Phase?

With Apparent Power (S) & Induced Emf per Phase (E_ph) we can find Current per Phase using the formula - Current per Phase = (Apparent Power*1000)/(Induced Emf per Phase*3).

Can the Current per Phase be negative?

Yes, the Current per Phase, measured in Electric Current can be negative.

Which unit is used to measure Current per Phase?

Current per Phase is usually measured using the Ampere[A] for Electric Current. Milliampere[A], Microampere[A], Centiampere[A] are the few other units in which Current per Phase can be measured.
