How do you calculate the total resistance?

Homework Statement

What is the Total resistance in Question 38.

Homework Equations

The Attempt at a Solution

I tried drawing the circuit again splitting up the series and parallel but i got the wrong answer. The answer is 92. Like i know that the 60 is parallen to 15 and the 15 is parallel to 10. The 15 and 5 are in series and the 20 and 10 are in series and maybe also 5. [/B]

What is the Total resistance in Question 38.

Homework Equations

The Attempt at a Solution

I tried drawing the circuit again splitting up the series and parallel but i got 93. The answer is 92. Like i did 40 + 40 + 10+ 1/((1/60)+(1/15) + 1/20 + 1/10 + 1/5)[/B]

You took all the 60 Ω, 15Ω, 20Ω, 10Ω, 5 Ω resistors parallel; they are not.

So what now

The ammeter can be replaced by a single wire. How are the 10Ω and 20Ω resistors connected?

Well, it doesn't say. It's just in series judging by the diagram

You need to use the diagram.
Yes, they are in series. What is their resultant? How that resultant is connected to the 15 Ω resistor?

Resultant? like 10 + 20 = 30 ?

 

[ehild]

Resultant? like 10 + 20 = 30 ?

Yes. Now you replace the 10Ω and 20Ω resistors with their series equivalent. How is that 30Ω resistor connected to the 15Ω resistor?

I did this earlier. Is it correct

 

[ehild]

I did this earlier. Is it correct

The diagram is correct. What is the result?

 

[Zoro]

The diagram is correct. What is the result?

80 + 1/ (1/60 + (1/20) + (1/30) = 90 =/= 92

 

[ehild]

80 + 1/ (1/60 + (1/20) + (1/30) = 90 =/= 92

Yor calculation is wrong. How are the 30Ω and 15 Ω resistors connected?

 

[Zoro]

Yor calculation is worong. How are the 30Ω and 15 Ω resistors connected?

I quit. Good luck.

LOl. wtaf man. can you just stop beating around the bush and hit the turkey on the head already?

Forum rules don't allow us to just give you the answer. For why see..

Next step (as ehild said) is to figure out how the 30Ω and 15 Ω resistors are connected? Series? Parallel? Replace these two with their equivalent.
