2. Thermoplastic-sheathed cable - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic-sheathed_cable

   This does not include the uninsulated ground wire. For instance, if the cable lists "12-2 AWG", it means there are two insulated 12-gauge wires (a black and a white wire), plus a ground wire. If the label says "12-3", this cable has four conductors—three 12-gauge insulated wires and a bare copper ground wire. [5]

   The resistance of copper wire is approximately ⁠ 1 Ω / 1000 ft ⁠ for 10 AWG, ⁠ 10 Ω / 1000 ft ⁠ for 20 AWG, ⁠ 100 Ω / 1000 ft ⁠ for 30 AWG, and so on. [ 5 ] : 27 For an arbitrary gauge n , it's approximately 10 n /10 Ω per 10 000 ft .

   It held 20 × 25-shell cartons (500 total shells) of 12 gauge ammunition and weighed around 65 lbs (Dimensions: 15" Length × 10.375" Width × 9.75" Height; Volume: 0.88 Cubic Feet). Guard shells had either a brass base (base only) with a full paper hull or partial brass case (1" long) and a long paper hull.

   Also, the size of the aluminum wire needs to be larger compared to copper wire used for the same circuit due to the increased resistance of the aluminum alloys. For example, a 15 A branch circuit supplying standard lighting fixtures can be installed with either #14 AWG copper building wire or #12 AWG aluminum building wire according to the NEC ...

7. Speaker wire - Wikipedia

   en.wikipedia.org/wiki/Speaker_wire

   Ordinary lamp cord has an inductance of 0.1–0.2 μH/ft, likewise for shielded cord, [6] so a run of up to about 10 feet (20 total feet of conductor) will have less than 1% inductive loss in the audible range (10 ft * 0.2 μH/ft = 2.0 μH, which is at or below the proximate threshold of 2 μH given above). Some premium speaker cables have ...
