Half Wave & Full Wave Rectifers

[chamwoods]

WHAT happen if i don't put resistor in circurt. The Voltage is same ?

They are O.K to charge battery ?

Thanks for posting.

@chamwoods Without the resistor the voltage would climb to the peak voltage which would be higher.

The resistor keep the voltage output mor or less constant.

Charging a battery would depend on the battery, the voltage output of the power supply, etc.

im an apprentice electrician in my 4th period of technical training in school and part of our course is electronics...i was struggling to comprehend some of this stuff and this video has certainly helped to make it easier to understand...we've done labs with capacitor filters and got the same output on our oscilliscope.....the 'sawtooth' wave...i cant wait to see more so i can kick some butt in the electronics portion of the course as it is a fairly large part of the final exam...thanks again!..

Thank you for your video.

Other videos I've watched say NOTHING about the center tap of the transformer, this helps my confusion.

So is it correct then that you MUST have a center tap transformer for full wave (cycle) rectification?

[old64goat]

@joshstube Yes because you have to have a RETURN circuit, the C.T. provides this and is often the negitive common, but may not be a chassis ground, depending on the circuit.

@joshstube No you do not need a center tap transformer to use a full wave bridge rectifier. Instead of using the center tap (which really is only cutting the voltage on the secondary in half depending on it's location in the winding), you can use ground as the return and use the full value of the secondary.

Thanks for your channel, I've been watching it for a while. They just didn't teach this in school when I went. I learned some from my grandfather who was a radio operator in the Army, but not much more than that.

Excellent job explaining. I have a 1964 Fender Vibroverb that the tube rectifier was converted to diode. The amps output is around 10 watts RMS more. Stevie Ray Vaughn had this done to his Vibroverbs and now I know why. Thanks again for the great job explaining!

@badaxxe, THANKS glad it was of some help to you.

Very interesting, Bill, thanks for that. I'm not into old radios, but I have old (early 60s) guitar amps that have tube rectifiers, so I really appreciate this. When did full wave rectification start to appear?

[old64goat]

@Barnekkid , Off hand I don;t know but I am sure it was around for a very long time.

Great video! I am still fairly new to electronics but this video was very well explained.

[old64goat]

@Alex1M6 Thank You very much.

Hello Bill, very good his explanation of the rectifiers, which was absent, that probably you forgot, or there do not use it maybe, it is the bridge rectifier of 4 diodes, for transformer without medium point, here it is used very much, any doubt that has on modern electronics and semiconductors consult me, I am technician in electronic, good luck friend ....... regards....

@fernando140887, Hi Fernando, I did not forget about the bridge rectifer, I just wanted to touch on the basics.

Thanks for watching.

thanks Bill, to bad that you don't have your shop aneymore.

i Don't know aneything about radios, so i like your videos

[old64goat]

@MrBrendog67rat, Yes I do miss having the old shop, I still have lots of stuff up in the old shop but I just do not have the room to take it.

When you rent you can't just build a shop.

If I owened the land we on on I would have a BIG shop sitting in my back yard....Just dreaming.
