Which formula represents the transformer law for voltage?

• A. Voltage (primary) / Voltage (secondary) = number of turns (primary) / number of turns (secondary)
• B. Voltage (secondary) / Voltage (primary) = number of turns (secondary) / number of turns (primary)
• C. Voltage (primary) x number of turns (secondary) = Voltage (secondary) x number of turns (primary)
• D. Voltage (secondary) = Voltage (primary) + number of turns (primary)

Answer: (B)

The transformer law for voltage describes the relationship between the primary and secondary voltages of a transformer in relation to the number of turns in their respective coils. The correct formulation states that the ratio of the secondary voltage to the primary voltage is equal to the ratio of the number of turns in the secondary coil to the number of turns in the primary coil. This is mathematically represented as: Voltage (secondary) / Voltage (primary) = number of turns (secondary) / number of turns (primary). This relationship clarifies that when a transformer steps up or steps down voltage, it does so proportionately with the number of turns in the windings. In practical terms, if the secondary winding has more turns than the primary winding, the voltage on the secondary side will be greater than the primary side, indicative of a step-up transformer. Understanding this principle is essential for designing and analyzing transformers used in various electrical applications, including medical imaging technologies where transformers play a critical role in powering equipment efficiently.
