  1. Hello. I want to make a transformerless power supply and have surf the web on it but the major problem here is that when driving a load is it not necessary to include the output voltage of the supply as a parameter? Is the supply going to come down to the voltage of the load? e.g a transformerless power supply with 334j x rated capacitor having a current of 23mA connected to 10led in series having characteristic drop of 1.5v at 15mA. Now, how can I calculate the value of the current limiting resistor? Thanks
