What is Wiring: Definition and 167 Discussions

Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure.
Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals.
Associated circuit protection, control and distribution devices within a building's wiring system are subject to voltage, current and functional specification. Wiring safety codes vary by locality, country or region. The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards amongst member countries, but significant variations in design and installation requirements still exist.

    Wiring a DC motor to two 9 volt batteries

    Hey everyone. I'm a beginner when it comes to making stuff with motors and batteries. Could anyone give me a link or a very good explanation on how to wire a 9 volt DC motor to 2 9V batteries (that are supposed to be wired in parallel) to power a propeller? I have the motors and the batteries...

    Neuron-Inspired Silicon Technology: 60 Layers for Enhanced Interconnectivity

    Human neurons have fanouts of like 5000. Transistors in CPU have fanouts of like 3 with 10 as a large number. Humans have like 60 wiring layers in the six layers of neurons of the neocortex. Chips have like 8. When will we see silicon technology with 60 layers and interconnectivity like neurons?
