This is when the symptoms of mild spinal stenosis are felt, such as occasional back pain, neck pain and leg pain. These symptoms are uncomfortable, but typically do not get in the way of a personâs normal daily activities such as sitting, standing, walking, working, etc.pinal stenosis is a gradual disease that is largely caused by the normal aging process. Over time, age-related conditions like arthritis of the spine, disc degeneration, bulging discs, etc. begin to encroach on the spinal column, causing it to become narrow.
The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor.n object of uniform cross section has a resistance proportional to its resistivity and length and inversely proportional to its cross-sectional area. All materials show some resistance, except for superconductors, which have a resistance of zero.
Prelab Exercises: 1. Calculate the resistance (in ohms) of a resistor that is part of a circuit with a voltage of 5V and a current of 940 mA. 2. Given the following resistor, decode its resistance value using the Electronic Color Code link given on the previous page: 3.

As you may have guessed from the name, an LED is a diode that emits light when current flows through it. Each kind of LED takes a specific voltage to light up, usually between 0.5V and 2V.
