Effect of frequency change on electrical transformer ... Say a transformer is designed for 50 Hz frequency but if the frequency becomes high or low what would happen. The voltage of a transformer has a proportional relationship with frequency. Voltage of a transformer at a given flux density increases with frequency and also decreases with it. We can get this from Transformer universal emf equation.
