Eye Strain. When you stare at screens all day, your eyes can get tired. Take a break with the 20/20/20 rule. Look at an object at least 20 feet away for 20 seconds every 20 minutes, says Ivan Schwab, MD, a spokesman for the American Academy of Ophthalmology.
Once you have the dial on your volt meter set to measure voltage, simply touch the black lead to the negative (-) terminal on your battery and the red lead to the positive ( ) terminal on your battery.
The basic unit of measurement for static electricity is the volt. The numbers are often so high that the kilovolt (Kv) is a commonly used unit. Typical Electrostatic Voltages at 20% Relative Humidity. 1  Sliding across a foam cushion 10-14 Kv. 2  Walking across a vinyl floor 8-12 Kv. 3  Walking across nylon carpet 2-4 Kv.
