Last year one of my battery drills gave up the ghost so I chucked it. I have just discovered the charger in the cupboard with the others. If I open it up will I find a transformer 240/12 volt and, more importantly a rectifier. If so what will they look like? |

MAYBE...
It will be a transformer (UK-220VAC to battery Volts + about 20%), fed to a very small bridge rectifier, then possibly a cap, then to a large watt resistor to limit the amps (so the transformer and battery don't fry), then to the battery.
Better chargers have a few more parts.
Much better (or at least newer) chargers have a LOT more parts. Most are so tiny they can't be re-used by us.
The bridge rectifier is probably too low in amps and volts to be of use for most items (windmills).
Like Victor said, it could be very handy later.

I'll keep it intact for the moment.
What a great explanatory site. Just the job to start my electronics education. I'll be talking amps and watts in no time!!

Some good pages on the link about components and what they look like.....
Keep your drill thing in one piece..might come in handy later for another use. :-) |
