Primary Current given Voltage Transformation Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Primary Current = Secondary Current*Transformation Ratio
I₁ = I₂*K
This formula uses 3 Variables

Variables Used

Primary Current - (Measured in Ampere) - Primary Current is the current which is flow in the primary winding of the transformer. The primary current of the transformer is dictated by the load current.
Secondary Current - (Measured in Ampere) - Secondary Current is the current which is flows in the secondary winding of transformer.
Transformation Ratio - The Transformation Ratio of the transformer is used to find the relation between primary voltage and secondary voltage.

STEP 1: Convert Input(s) to Base Unit

Secondary Current: 10.5 Ampere --> 10.5 Ampere No Conversion Required
Transformation Ratio: 1.2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I₁ = I₂*K --> 10.5*1.2

Evaluating ... ...
