## Transformer Calculator. Description
Transformer Calculator: A user-friendly app for Current and Voltage Calculations.

Current Calculations
 • Calculate primary and secondary full-load currents.
 • Determine the turns ratio and transformer type.

How it works:
 1. Select the phase type (1Φ or 3Φ).
 2. Input transformer ratings (VA/kVA) and primary/secondary voltages.

Outputs:
 • Primary full-load current
 • Secondary full-load current
 • Turns Ratio:  N1 / N2 = V1 / V2 = I2/ I1

Voltage Calculations
How it works:
 1. Enter Number of turns in the primary and secondary windings
 2. Input Primary voltage

Outputs:
 • Secondary voltage
 • Turns Ratio: N1 / N2 = V1 / V2 = I2/ I1

Effortless and Accurate: Perfect for engineers and students to compute transformer parameters precisely.
