Transformer vs Potential divider
I got bored and decided to make a study table light using LED's. My setup consists of 4 LED's in an arm and 10 such arms in parallel. I actually designed it in view that the transformer i used converts 230v - 15v. But after it all finished, i found out that all my transformers are used up for other circuits. I was wondering,
Can i use a potential divider for such simple circuits?
I approximated that if i place a 46K and a 3K resistor in series and take the voltage across the 3k resistor, i will have about 15 v.
What are the disadvantages of using such potential divider?
