This is not a job for an amateur, but I will help you with some primary considerations. My answers are based on the United States' NEC (code) and do not take into consideration any local requirements.
You do not want to extend your existing service conductors. You want to install a 100amp breaker into your existing panel and run conductors from there to your new panel.
If this is a residential application you can run this with #4 copper conductors. If this is a commercial application you must run #3 copper conductors. I would answer this question based on what your shop is intended to do. If you are running professional equipment and are more or less "in business", use the commercial requirements.
If you know how to properly ground a new service, and if your new panel has a main breaker, you can do what you need with 3 conductors. This will allow you to put neutral and ground conductors on the ground bar like you would in your primary panel. If you do not know how to properly ground a new service or doing so is not practical, you will need 4 conductors and your grounds and neutrals will have to be ISOLATED from each other in the new panel. Your neutral bar in this case would be insulated from the panel. In this case your new panel would become a sub-panel of the primary panel.
Some panels do not have a main breaker and this is a critical consideration if you intend to wire it as a new service. Personally, I wouldn't install a panel without a main breaker whether or not it is a service or sub-panel.
it depends it could be 30ft or even 300ft
running wire 12-2 300ft w/9ea. 27watt lights what size breaker should be used
20amps but Voltage at end of cable will drop. Not a problem for incandescent lights but might be a problem for motors and electronics. Generally increase wire size to next larger size for long runs, I.e. go to 10# wire. This does not factor in heating in wire under heavy load, but that is generally not a factor unless tightly enclosed.
That is 10,800 square feet and there are 43,560 square feet in one acre. Your example would be about 1/4 of one acre. 0.2479 to be exact.
No. Bluetooth is designed for very low power use, and the transmission range is typically only around 10m (about 30ft). High-powered Bluetooth devices will enable ranges up to 100m (300ft). Considering the design philosophy behind Bluetooth, even the 10m range is adequate for the purposes Bluetooth is intended for. Cellphones must be able to communicate reliably with the nearest cellular tower. Transmit power output can range up to as much as a few watts.
