How Does an Electrical Transformer Work?
Basic Operating Principle
An electrical transformer operates on Faraday's Law of Electromagnetic Induction:
-
AC current flows through the primary winding, creating a magnetic field
-
Ferromagnetic core channels the magnetic flux to the secondary winding
-
Voltage induction occurs in the secondary coil (step-up or step-down)
-
Power transfer happens without direct electrical connection
Transformer Equation
V₁/V₂ = N₁/N₂
Where:
-
V = Voltage
-
N = Number of winding turns

FAQ: How Does an Electrical Transformer Work?
Q: What factors determine transformer efficiency?
A: Key efficiency factors include:
-
Core material quality (low hysteresis loss)
-
Winding conductor type (copper vs aluminum)
-
Load ratio (peak efficiency at 50-75% load)
-
Cooling method (liquid vs air cooling)
-
Design standards (IEC 60076, DOE 2016)
