Answer

Rectification : Rectification is the process by which alternating current (voltage) is converted into direct current (voltage). The device used for this is called rectifier. A (P-N) junction diode conducts current in forward bias and does not conduct current in reverse bias (negligible current). This unidirectional property of diode is used in rectification.
