w

Wafer: Refers to a thin semiconductor material layer obtained by sawing one solid crystal or multi-crystal casting or ingot using a mechanical device.

Watt / W: Refers to a unit of electricity equaling 1 joule per second. Hence, when 1 ampere of current flows at a possible strength of 1 volt, it can produce a power of 1 watt.

Watt-hour / Wh: It is a measure of electrical energy equivalent to a power consumption of one watt for an hour.

Waveform: Refers to the shape generated by the curve that graphically represents the difference in current amplitude and AC voltage against time.
