Is the turns ratio of a transformer directly proportional to current?

The turns ratio of a transformer is not directly proportional to current. In a transformer, the turns ratio refers to the ratio of the number of coils (or turns) in the primary winding to the number of coils in the secondary winding. This ratio affects the voltage and current in the transformer according to the principle of electromagnetic induction.

Specifically, the current in the primary and secondary windings is inversely related to the turns ratio. If the turns ratio increases (more turns in the primary winding compared to the secondary), the voltage in the secondary will be greater, but the current will decrease. Conversely, a lower turns ratio (fewer turns in the primary compared to the secondary) results in a lower voltage but higher current in the secondary. This inverse relationship is a fundamental characteristic of how transformers operate, adhering to the principle of conservation of energy where the power output (voltage multiplied by current in the secondary) must equal the power input (voltage multiplied by current in the primary), disregarding losses.

Understanding this inverse relationship clarifies why the statement regarding the direct proportionality of the turns ratio to current is false. It also illustrates the importance of using transformers effectively in power distribution systems, where adjustments of voltage and current are crucial for efficiency and safety
