Equivalent resistance Definition and 207 Threads

I'm not sure if I'm doing this right, I would appreciate if someone could take a look. Q. Find the equivalent resistance of the circuit (attached diagram). Each of the six resistors has a resistance equal to 12 ohms. I'm thinking that R5 and R6 are in series and therefore combine to be 2R...

Find the equivalent resistance between points A and B for the group of resistors shown in Figure 21-29, where R1 = 93 and R2 = 40 . http://server5.ihostphotos.com/show.php?id=fW6dc414515Bf2aS6b42f0eGf8aad2e7 ok i know that R_{1} and 35\Omega are in series and R_{2} is in parallel to the top...

Can two resistors in series be replaced by a single resistor and give an equivalent resistance to the circuit? If so , how must the single resistance be related to the two in series ? R=R1+R2 ? ?

I'm in a intro to circuits class for non-EE majors. One of the homework problems asks for the equivalent resistance. See the attached file for a picture of this system. I know the first step is to add resistors R4 and R5 (in series) as well as add resistors R6 and R7 (in series). But...

For this question I am pretty sure I am doing everything right but I just can't get the right answer. Diagram below. This is the question. Find the equivalent resistance of the circuit shown in the diagram, where R1 = 3 Ω, R2 = 2 Ω, R3 = 4 Ω, R4 = 1 Ω, R5 = 1 Ω, R6 = 2 Ω, and R7 = 2 Ω. What I...

ok, so the problem states: the current in a loop circuit that has a resistance of R1 is 3A. The current is reduced to 1.6A when an additional resistor R2=2ohms is added in series with R1. What is the value of R1? I drew two diagrams. My logic was that the voltage would be the same, b/c the...

I'm stumped by this problem. There's no symmetry in the circuit, so I can't ignore the 1 ohm resistor that bisects the triangle. Is there something else I'm missing? I'm supposed to show the Rab = 27/17 ohms. Please see the attached diagram. Thanks.
