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.
Light Emitting Diode
CONNECTING A LED
A LED must be connected around the correct way in a circuit and it must have a resistor to limit the current.
The LED in the first diagram does not illuminate because ... readmore
