Revise: Transformer Power EquationAn ideal transformer is assumed to be 100% efficient: all the power entering the primary is transferred to the secondary.
Physics, Combined Science
A transformer that is 100% efficient, so its electrical output power equals its electrical input power.
Check that a higher secondary potential difference gives a lower secondary current than the primary current for an ideal transformer.
