OK so, Ive been scavenging the web all night and i cannot find the answer to my question and it is getting very frustrating. So here it is.
How would i go about creating a circuit that charges the battery while plugged in but the device the battery was powering can still be used while plugged into the wall.. cellphones do this, battery powered headphones do this, a lot of things use this feature yet i cant find it on the web. I was thinking that maybe a transistor would play a roll in this? While plugged in the transistor switches the discharge from the battery off while the wall power takes over. i dont know. please help..
