Answer Details
A semiconductor diode is used in rectifying alternating current into direct current mainly because it allows current to flow only in one direction. This is because a diode has a characteristic property of conducting current in one direction and blocking it in the opposite direction. When an AC voltage is applied across the diode, it allows the current to flow only during the positive half cycle and blocks it during the negative half cycle. As a result, the diode acts as a rectifier, converting AC voltage into DC voltage.
