Hi,
I made an AC to DC adapter using a (12v-0-12v)transformer, a 2200uF capacitor, a bridge diode and voltage regulators etc. But current out of the regulators are 1000 mA. I need 400 mA current.
I tried by using a 56 ohm resistor in parallel. But that becomes too hot and doesn't work.
What's wrong with the parallel resistor? How can I limit the current?
Thanks in advance
