In a series circuit, the current remains constant, but a transformer operates differently as it consists of two magnetically coupled loops, not a single series circuit. The primary and secondary circuits are independent, allowing for different currents while conserving electric charge. When a transformer increases voltage, it decreases current proportionally to maintain the same power output, as described by the relationship P=VI (Power = Voltage x Current). Understanding Lenz's law and the power flow mechanism is crucial for grasping how transformers function. This distinction clarifies the misconception about current behavior in transformers compared to series circuits.
