1
00:00:00.000 --> 00:00:05.610
One route: series. Two 1000-ohm resistors in series give the current

2
00:00:05.610 --> 00:00:09.691
one path. Their resistances add to 2000 ohms.

3
00:00:10.091 --> 00:00:15.599
Two routes: parallel. Two equal 1000-ohm resistors in parallel give two

4
00:00:15.599 --> 00:00:20.607
paths between the same nodes. The total is 500 ohms.

5
00:00:21.007 --> 00:00:26.111
What stays the same?. Series components share the same current. Parallel

6
00:00:26.111 --> 00:00:29.823
branches share the same voltage across their endpoints.

7
00:00:30.223 --> 00:00:34.463
Draw the nodes. The electrical connections matter more than the shape

8
00:00:34.463 --> 00:00:37.932
of the drawing. Trace which terminals share a node.
