What is the net resistance of the circuit connected to the battery in Fig. 19-33? Each resistance has R = 3.0?
Start by adding the two in series between A and B

Req=6K

then that is in parallel with one 3 K

Req=18/9=2K

that is in series now with one 3 k

Req=5K

then that is in parallel with one 3 K

Req=15/8



and that is in series with one 3 k

Req=3+15/8

Req=4.875 kΩ
