How it works

3rd experiment

How to explode, blow the lamps/LEDS) = (1) up the voltage; (2) even just to 6.12 volts (love this software!)

(3) setting 6V, +33 amps, 1.09 K ohms

(4) changed to 4.7K ohms, current 8.009A, working

(5) Let's add another LED (a) in series, what changes

6V, 4.7K ohms = 3.483 A, nice.

6V, 10k ohms = 1.728 A

3rd LED, 6V, 182.7mA but must reduce the resistance (also %) of the potentiometer, heading towards microAmps, LEDS going out.

Addition of an LED in the correct place. Mess around with where the LED can go into the circuit.

Got rid of the HotWire indication of 2 battery source (3V + 3V)

Leaving the resistance data from Experiment 1 for the moment.

So many variables, so little time, and so much knowledge beckons!

What's inside

  • 1× Battery
  • 8× LED
  • 1× Switch
  • 1× Potentiometer
