Designing a supercapacitor circuit
hi, i'm given a project assignment of building a supercapacitor which can store roughly 700V to 1000V. Now i'm designing a circuit (discharging) which can help me light up a few LEDs using Voltage charge stored in the supercapacitor. The purpose of the circuit is to show that the...- magicasd
