Concept:A rectifier uses the one-way conduction property of a p-n junction diode to convert alternating current into direct current.
Explanation:A p-n junction diode conducts current only when it is forward-biased and blocks current when it is reverse-biased.
When an alternating current (
a.c.) is supplied, the diode allows current to pass only during the positive half-cycle.
During the negative half-cycle, the diode becomes reverse-biased and stops the flow of current.
This produces a pulsating direct current (
d.c.) at the output.
Thus, a rectifier converts
a.c. to
d.c..
Answer:Option (A)
a.c. to
d.c.
