The process of converting alternating current (AC) electricity into direct current (DC) electricity is known as rectification. This involves the use of devices called rectifiers, which allow current to flow in only one direction, effectively transforming the AC waveform, which alternates between positive and negative voltages, into a unidirectional (DC) output.

Rectification can be achieved using various components, including diodes, which are semiconductor devices that conduct current in one direction while blocking it in the opposite direction. This is essential for many applications, such as powering electronic devices that require a stable DC voltage source, because most electronic components operate on DC.

Understanding this process is crucial for anyone working with electrical systems, as it underlies the operation of power supplies, battery chargers, and countless other devices that require a reliable DC voltage. The other options represent different electrical concepts: induction relates to the generation of current through electromagnetic induction, conversion is a broad term that lacks the specificity of rectification, and transformation refers to changing voltage levels in AC systems using transformers, not the conversion to DC.
