I have fabricated a super-capacitor electrode with good specific capacitance, cyclic stability, power density and energy density. I want to test it by lightning an LED. Can any one help me with the step by step procedure.
In order to glow a LED[1], for a short time, you can connect it, in series, with a number N of fabricated SC (independent, full) cells. Also, connect all these with a series[2] (imax-protection) resistor, R; some values[2] of R, you can use, are near 51Ω (or higher, protection), for an initial Voltage of, at least, 3V (=N*Vmax); the value of Vmax results from a single SC (charged) cell, supporting a minimum current of 10mA, for a small size (and glow power) LED.
1. say, a red color LED.
