3000 Volts or more. This comes directly from the A++ Hardware book.
From ESD Association ESD Handbook ESD TR20.20 section 5.3.2.1:
"When people are charged with static electricity, they can release stored energy to conductive objects such as doorknobs and electronic circuits. This transfer of energy is called an electrostatic discharge. Sometimes the electrostatic discharge causes visible sparks, but more often, it is both unseen and unfelt. Electrostatic discharges can damage ESD sensitive components used in modern electronics.
Static electricity is a natural phenomenon that occurs in all climates and at all levels of relative humidity year round. Most people cannot feel an electrostatic discharge unless the static voltage is greater than 2000 volts. However, some electronic circuitry can be damaged by ESD that is less than 2000 volts. The damage can be done without people having any sensation of the ESD event.
When a wrist strap is worn properly and connected to ground, the person wearing it will stay near ground potential."
A person can typically feel an electrostatic discharge when it reaches around 3,000 volts. This sensation is often described as a small shock or static electricity zap.
In order to prevent discharge into the air, the conducting sphere of the electrostatic generating machine must achieve a surface charge density sufficient to produce an electric field strength below the breakdown strength of air (typically 3 x 10^6 V/m). The minimum radius can be calculated using the formula for electric field E = k * Q / r^2, where k is the electrostatic constant, Q is the charge on the sphere, and r is the radius of the sphere. Given the charge Q = 23000 C, you can solve for r.
what is the minimum level of elecrostatic discharge that a person can normally feel? Per ESD Association ESD Handbook ESD TR20.20 section 5.3.2.1 "Static electricity is a natural phenomenon that occurs in all climates and at all levels of relative humidity year round. Most people cannot feel an electrostatic discharge unless the static voltage is greater than 2000 volts. However, some electronic circuitry can be damaged by ESD that is less than 2000 volts.

Supported minimum size in computer terms is referred to as the minimum system requirements or recommended system requirements. These tell the minimum amount of memory and free disk space as well as the minimum processor speed you need on your computer to run a particular software program.
minimum date is 1980. maximum date is 2099.
The difference is that the maximum is normally larger than the minimum.
Very less normally in few Bytes..
