shared-flux-change-sets-both-voltages - Electronic Circuits XV: Transformers and Coupled Inductors Step by Step

One ideal core flux-change source feeds both windings. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

Both windings cite one flux-change source

The flux change and interval are shared. Each winding multiplies that rate by its own turns.

V=N{\Delta\Phi\over\Delta t}

Each winding voltage follows its own turns

The flux-rate row stays fixed while the turn counts change together.

\begin{array}{c|c|c|c}N_p&N_s&V_p&V_s\\2&1&2\ \text{V}&1\ \text{V}\\4&2&4\ \text{V}&2\ \text{V}\\6&3&6\ \text{V}&3\ \text{V}\\\end{array}

One flux change sets both winding voltages

The checked row has one shared flux source, one interval, and two winding turn counts.
