hello everyone,
1:- in the below video i think the transformer used is called centre tap transformer. someone was telling me that the input voltage of 12V is divided between two voltages of 6V across the secondary coils. But at one time only one secondary coil is really conduction because the other one would one wouldn't be able to conduct because the diode is reverse biased.
hence i think at one time entire 12V appear across a single secondary coil instead of 6V.

if the video embedding does not work above then please use this link:
2:- actually in this diagram i am trying to understand functioning of centre tap transformer. i think when the light bulb 2 is not conducting, all of 12 volts are appearing across light bulb 1. but when light bulb is also conducting (i mean switch is closed) then only 6 volts will appear across both light bulbs (assuming both bulbs have same resistance). is this what i say correct?

many thanks for this help. much grateful, have been learning a lot from nice people here.
cheers
