Can someone help me create this conceptual circuit? Where..when electric power is brought in, it is stored, and that stored energy at the same time can be outsourced to a target at a particular amp/current/voltage needed to power that target, as well as allowing that excess stored energy to be outsourced to other "targets" I don't know how clear I'm being. I'm guessing I need a battery of some sort that can be charged with electricity. I'm just wary as I don't know if I can use the power from that battery for more than one thing. And one thing that I do want to power, I want control the level of electric strength/flow. And for the excess energy left in the battery, I want to use to power a e.g. light bulb. How could I do all this? I don't know what I need, transistors, capicitators? splitters?
