I need help with the properties of half wave, full wave: 2-diode bridge and 4- diode bridge rectifiers. also with advantages and disadvantages of both. thank you

 

What does your school book say about them?

 

I do not have a text book to consult regarding the question, what book do you recommend?

 

Start here:
