This video demonstrates the use of Ohm's Law to calculate current, voltage, and resistance in a simple circuit.
Note: I plan to redo this video with better graphics for circuit problems, it is hard to see the numbers on the low resolution versions like on Youtube.

A basic instruction for electronics enthusiasts. I use an RGB LED and a 510 ohm resistor as I may change from 6 to 9 volts later, but with my LEDs i could go as low as 330 ohms. I sacrifice some brightness for the sake of longer life. To choose your resistor, the value in ohms = voltage of your batteries or power supply / (as in divided by) the amperage that your LED needs to run

This amp powers in with 400W @ 4 Ohms, 280W @ 8 Ohms, 500W @ 2 Ohms. The three mode channels let you customize your sound:
Mode 3: A boosted overdrive with punishing gain and liquid sustain.
Mode 2: Classic overdrive channel for vintage to modern tube tone .
Mode 1: Full tube clean with warm tone and big headroom.
