Equivalent Resistance from Primary Side Solution

STEP 0: Pre-Calculation Summary

Formula Used

Equivalent Resistance from Primary = Resistance of Primary+Resistance of Secondary/Transformation Ratio^2
R₀₁ = R₁+R₂/K^2
This formula uses 4 Variables

Variables Used

Equivalent Resistance from Primary - (Measured in Ohm) - The Equivalent Resistance from Primary side is the total resistance of the primary side.
Resistance of Primary - (Measured in Ohm) - Resistance of Primary Winding is the resistance of primary winding.
Resistance of Secondary - (Measured in Ohm) - Resistance of Secondary Winding is the resistance of secondary winding.
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

Resistance of Primary: 17.98 Ohm --> 17.98 Ohm No Conversion Required
Resistance of Secondary: 25.9 Ohm --> 25.9 Ohm No Conversion Required
Transformation Ratio: 1.2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R₀₁ = R₁+R₂/K^2 --> 17.98+25.9/1.2^2

What type of windings are used in a transformer?

In core type, we wrap the primary, and secondary windings on the outside limbs, and in shell type, we place the primary and secondary windings on the inner limbs. We use concentric type windings in core type transformer. We place a low voltage winding near the core. However, to reduce leakage reactance, windings can be interlaced.
