A transformer cannot operate with direct current (DC) due to the nature of magnetic flux and its relationship with current. When a direct current flows through the primary winding, it generates a constant magnetic field, resulting in no change in magnetic flux. According to Ampere's law, the induced voltage in the secondary coil is directly proportional to the rate of change of magnetic flux; thus, without a changing flux, no voltage or current is produced in the secondary coil. This principle explains why a generator must be in motion to induce current in its coil.
PREREQUISITESElectrical engineers, physics students, and anyone interested in understanding the principles of transformers and electromagnetic induction.
Why do you need a generator spinning to have current in its coil?kekkeroo said:why doesn't the magnetic flux going through the core result in a current in the secondary coil
