RMS Current using Real Power Solution

Follow our step by step solution on how to calculate RMS Current using Real Power?

FIRST Step Consider the formula

I rms = \frac{P}{V rms \cdot \cos (Φ)}

Next Step Substitute values of Variables

∴

I rms = \frac{235W}{57.5V \cdot \cos (30°)}

Next Step Convert Units

∴

I rms = \frac{235W}{57.5V \cdot \cos (0.5236rad)}

Next Step Prepare to Evaluate

∴

I rms = \frac{235}{57.5 \cdot \cos (0.5236)}

Next Step Evaluate

∴

I rms = 4.71921089598477A

LAST Step Rounding Answer

∴

I rms = 4.7192A
