Hello, I realize this may appear as homework but I assure you that it is not for school. However i am new to the site so please let me know if i interpreted the rules wrong. I'm a mechanical EIT whose electrical engineering education ended in about second year when general studies were concluded. Its been years since I've used the information within and school never really focused on creating the circuits just solving them. For work I'm trying to come up with a (relatively) simple circuit to power two motors and a set of LED lights using DC batteries and a solar panel. My issue is that the lights require 12V while the motors require 24V each. Attached is a sketch of what i believe is a viable solution. The lights use 540mA. If i remember my formulas right that means that to "get rid" of 12V i would need a 22.2Ω resistor. (12/0.54 = 22.2). Basically all I'm wondering is if my logic is sound or if I'm totally off base. Thank you.
