True or False - The primary side of a transformer has high voltage and large current.

The primary side of a transformer is generally characterized by high voltage and lower current, especially in the case of step-down transformers. This is a fundamental principle in transformer operation, as transformers work on the principle of electromagnetic induction.

In a step-up transformer, the primary side does experience low voltage and high current while the secondary side has high voltage and low current. Conversely, in a step-down transformer, the primary side has high voltage and low current, while the secondary side has a lower voltage and higher current.

This relationship is governed by the turns ratio of the transformer. For every turn of wire on the primary coil, there will be a corresponding turn on the secondary coil, which determines the voltage transformation — based on the equation relating voltage and turns: Vp/Vs = Np/Ns, where V is voltage, and N is the number of turns.

Thus, stating that the primary side has high voltage and large current is incorrect in the context of typical transformer operation, making the correct answer true.
