Im building a AC to DC battery AA charger using a full wave rectifier and a 5v regulator. Im wanting to charge 3 AA batteries. There 1.2V each with 2450mAH. So i was wanting to charge them at a rate of 245mA. The problem im having is, how would i make the output of the 5v voltage regulator output the 245mA of current. Do i put in a 20 ohm resistor (5v/20ohm=245mA) on the output and then connect the batteries to it. Any help would be appreciated. Thanks
