2. High resistance in the primary or secondary coil: High resistance in the primary or secondary coil will reduce the current flow and, consequently, the voltage. This can be caused by a number of factors, such as damaged or corroded wires, loose connections, or a faulty transformer core.
3. Incorrect turns ratio: The turns ratio of a transformer determines the voltage step-up or step-down ratio. If the turns ratio is incorrect, the secondary coil voltage will not be as expected.
4. Magnetic saturation: When the magnetic core of a transformer becomes saturated, it can no longer support any further increase in magnetic flux. This can cause the secondary coil voltage to drop.
5. Stray magnetic field: A stray magnetic field can interfere with the magnetic field in the transformer core, causing the secondary coil voltage to drop. This can be caused by nearby metal objects, such as tools or machinery.
