Hi all,
It has been many years since my GCSE electronics and so I apologise if this is a very stupid question...
I want to replace 3 AA batteries in a torch, with a plugged in supply, and I am having trouble finding a suitable adapter. I know that I need a 4.5V supply (3 x AA) and have read that the current is typically 900mA from AA batteries.
I have found a 4.5V 1200mA adapter. Is this going to destroy the LED bulb / circuitry or am I being a muppet?
I have also found a 5V , 900mA adapter. I assume this is worse..?
Thanks for your help
