Hey guys, i'm totally new here, kind of newbie in electronics and this question is very probably dumb.
I opened my stun gun to see what was inside, and was confused by the battery charging process.
The unit is to be plugged directly into a 110V AC outlet, and the battery inside is made of 4 little batteries packed together, each one being 1.2V (according to the multimeter), for a total of about 5 volts.
Then it seems to me that in order to charge those batteries, the current has to be turned from 110V AC to 5V DC.
The thing is, I followed the path from the charging prongs to the batteries, and it only passes through a capacitor and a bridge rectifier.
So 110V AC enters, and my batteries receive 110V DC ?
Does the combo capacitor/bridge rectifier lowers the voltage (I don't believe so, I read that it just turned AC into DC then smoothes the output) or is it okay for the batteries to receive more than 20 times their voltage ? Help me understand how it works
The capacitor is a 400V HXDCBB22 and the bridge rectifier is a DB107.
I tried to draw the circuit:
(The resistor is for the LED, I don't think it interfers with the rest)
And by the way, do you think I can plug it into a 220V power outlet ?
Thank you !
