Basic Electricity For Homeowners

Worth1 · January 28, 2017

Now if you were to get in a bind and needed to run a car radio tape player off 12 volt power in the house you would need this stuff.
I was in that bind and at the young poor age of 13 I did it.
I took a 6 amp 12 volt car battery charger and hooked it up.
What the devil is that buzzing noise?

?!?:
Well it was that dreaded AC ripple I talked about.
That buzz was unfiltered DC current the buzz is the polarity swapping 60 times a second.
Now how to filter it out.
I took a dead cant charge anymore car battery and ran my charger to it.
And then to the tape player.
This killed out all of the AC ripple and in effect I had a filter as a battery and capacitor which is used for a filter are a lot alike.

Yes I had a lot of crazy stuff in my room growing up.
Dried bugs and critter collections pet frogs strange mold experiments and electrical stuff and occasional controlled explosions and fires.
