hi
im repairing my simple nicad charger that melted its current output resistor due to a bad battery pack. the transformer i believe is a 12-0-12 center tap and is full wave rectified using 2 diodes. the battery pack is 9.6v 1.3ah. the sticker on the case says output 11.6v. how do i calculate the resistor. is it done to get 11.6v@1.3a
or is it done at the batteries voltage of 9.6v @'1.3a. what im unsure about is whether the battery is charged at its rated voltage or does it have to be 2 volts above at 11.6 v.
