In the transformer equation, which variable represents input potential difference?

In the context of transformers, the variable that represents the input potential difference is denoted as Vp. In a transformer, there are two key voltages: the primary voltage (Vp) and the secondary voltage (Vs). The primary voltage is the voltage applied to the primary coil of the transformer, which produces a magnetic field that induces a voltage in the secondary coil.

Transformers work on the principle of electromagnetic induction, and the relationship between the primary and secondary voltages is expressed through the transformer equation, which relates these voltages to the number of turns in the primary and secondary coils. Understanding this relationship is crucial, as it helps in determining how a transformer can increase or decrease voltage based on its design.

The primary voltage (Vp) is critical in determining how effectively the transformer can function and how much voltage is induced in the secondary coil. Thus, identifying Vp as the variable that represents the input potential difference is essential for comprehending the workings of transformers.
