8
00:00:25,040 --> 00:00:29,960
Speaker 1: today's question, can you explain the diameter measurements used in wire?

9
00:00:30,600 --> 00:00:34,080
Speaker 1: The measurement system used for wire is interesting. A w

10
00:00:34,320 --> 00:00:39,080
Speaker 1: G stands for American wire gauge and is the standard

11
00:00:39,120 --> 00:00:42,159
Speaker 1: in the United States for wire diameters and how she

12
00:00:42,280 --> 00:00:46,760
Speaker 1: typically find ten, twelve, and fourteen gauge wire and electronics

13
00:00:46,800 --> 00:00:51,920
Speaker 1: projects typically used twenty gauge wire. Wire gauges run from

14
00:00:51,920 --> 00:00:55,400
Speaker 1: O O O gauge, which is about a half an

15
00:00:55,440 --> 00:00:58,600
Speaker 1: inch in diameter, down to forty gauge, which is about

16
00:00:58,760 --> 00:01:02,000
Speaker 1: point o O one in inches or a thousand of

17
00:01:02,040 --> 00:01:05,679
Speaker 1: an inch in diameter. The higher the AWG number, the

18
00:01:05,720 --> 00:01:09,720
Speaker 1: thinner the wire. Where did this odds system come from?

19
00:01:09,760 --> 00:01:13,119
Speaker 1: It has to do with the way wire was once made.

20
00:01:13,640 --> 00:01:17,120
Speaker 1: Wire is drawn through dies to make it thinner. The

21
00:01:17,160 --> 00:01:20,319
Speaker 1: more dies, the thinner the wire. The gauge number stems

22
00:01:20,360 --> 00:01:23,440
Speaker 1: from how many holes the wire is drawn through when

23
00:01:23,440 --> 00:01:27,000
Speaker 1: it's manufactured. Do you have any ideas or suggestions for
