Ideal Transformer Current Equation

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage in a second coil.

The ratio of turns in the primary coil to turns in the secondary coil equals the ratio between the secondary current and the primary current.

Formula

QuantityVariable[Subscript["N", "1"], "Unitless"]/QuantityVariable[Subscript["N", "2"], "Unitless"] == QuantityVariable[Subscript["I", "2"], "ElectricCurrent"]/QuantityVariable[Subscript["I", "1"], "ElectricCurrent"]

symbol description physical quantity
N1 primary turns "Unitless"
N2 secondary turns "Unitless"
I1 primary current "ElectricCurrent"
I2 secondary current "ElectricCurrent"
