... The results show voltage is stepped (up, down) from primary to secondary, and that the current is stepped (up, down) to compensate. For a step-up transformer, there are (more, fewer) turns in the secondary coil than the primary coil. For such a transformer, there is (more, less) current in the secon ...

High voltage
The term high voltage usually means electrical energy at voltages high enough to inflict harm on living organisms. Equipment and conductors that carry high voltage warrant particular safety requirements and procedures. In certain industries, high voltage means voltage above a particular threshold (see below). High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to demonstrate arcing, for ignition, in photomultiplier tubes, and in high power amplifier vacuum tubes and other industrial and scientific applications.
