(rek´ti-fī´´&r) (n.) A component of a circuit that allows current to pass in one direction yet blocks the flow of current in the other direction. Rectifiers are used to convert AC into DC

Rectifier is a term applied to several devices. The most common is a solid state diode. In the earely days of electronics there were gas filled diodes. Both have a cathode and an anode.
When the cathode is more negative than the anode it will conduct electricity. When the cathode is positive in respect to the anode it won't conduct.
The most common use is to convert AC voltage to DC voltage(with the help of a couple other components to shooth out the ripple). There are half wave rectifiers that consist of a single diode that conducts only during one half cycle. Full wave rectifiers have two diodes each conducts during one half of the AC cycle and has to have a center tapped transformer. Full wave bridge rectifiers consist of four diodes and do not have to have a center tapped transformer.
I hope that gets you started.

The term rectifier is sometimes applied to other devices but specifically a rectifier is a combination of diodes used to convert AC voltage to DC voltage. The rectifier is either half-wave or full-wave. Half wave converts one half of the sine wave to DC, and requires a single diode; A Full wave (bridge rectifier) converts the entire sine wave to DC voltage and requires 4 diodes. Additional components such as capacitors are not part of the rectifier, but are used to smooth the output of the rectifier to a stable dc voltage.

A rectifier is diode circuit designed to get dc out put from an ac input. There is full wave and half wave rectifiers. Full wave rectifiers are bridge rectifiers and half wave rectifiers are single diode rectifiers. It is used in power supplies of electronic systems.

The rectifier is an electronic circuit which convert ac current to dc current, and the main components of it is the diodes and capacitors.

can the diode of a rectifier go bad if connected wrong?

In my day it was used to convert ac voltage to dc voltage in an alternator,i hope this helps.
