Primary Current using Primary Parameters Solution

Follow our step by step solution on how to calculate Primary Current using Primary Parameters?

FIRST Step Consider the formula

I 1 = \frac{V 1 - E 1}{Z 1}

Next Step Substitute values of Variables

∴

I 1 = \frac{240V - 13.2V}{18Ω}

Next Step Prepare to Evaluate

∴

I 1 = \frac{240 - 13.2}{18}

LAST Step Evaluate

∴

I 1 = 12.6A
