You bought a charger that does not have a charging satus indicator. Assuming that a regular rectifier circuit configuration (such as this: http://www.physics.udel.edu/~nowak/phys645/AC_circuits_files/image016.jpg ) is used for the charger, modify the rectifier circuit to have LED indicator(s) and explain how the modified circuit would work. 3. The attempt at a solution - I'm not at all sure on this one. I was originally thinking to add an LED in series with the load and explain that the load (rechargeable battery) would block the current once it was charged, and that would cause the LED to shut off, but I don't think that is how rechargeable batteries work. Can someone please help me on this one?
