Final answer:

The statement is false; in a step-down transformer, the primary side has a higher voltage and typically a smaller current compared to the secondary side, following the conservation of energy principle.

Step-by-step explanation:

The statement that the primary or high voltage side of a transformer has a large current and high electric pressure is false. Typically, in a step-down transformer, the primary side (connected to the high voltage or 'input') has a higher electric pressure (voltage) compared to the secondary side (the 'output'). However, the current on the primary side is not large; it's typically smaller than that of the secondary side. According to the principle of conservation of energy, and assuming that the transformer is nearly 100% efficient, the power output (Ps) equals the power input (Pp). This can be represented by the equation Pp = IpVp = IsVs = Ps, where I denotes current and V denotes voltage. For a step-down transformer, this means that as the voltage decreases from the primary to the secondary, the current increases.
