How to find effective resistance in a circuit.

AI Thread Summary
To find effective resistance in a circuit, it's crucial to determine the configuration of the resistors, whether they are in series or parallel. The discussion emphasizes the importance of visualizing the circuit clearly to identify symmetry and connections between resistors. Participants suggest checking each resistor's connections to clarify their arrangement. There is confusion regarding the values assigned to resistors, particularly a 1 Ohm resistor appearing as 100 Ohms. Clear diagrams and systematic analysis are essential for resolving these issues effectively.

Homework Equations


For parallel resistors: 1/R=1/R1 +1/R2

The Attempt at a Solution


I am sure the resistors are not in series but they also don't look convincing enough to be parallel. I am stuck.

You can draw them with a clearer arrangement, then some symmetry will be visible.
Alternatively, just check resistor by resistor: where is one side connected to? Where the other? Is this the same for any other resistor?

I've tried all that to no avail. Pls check the link.

That is not simplified, it is the same diagram as in the problem statement.

The 1 Ohm resistor got 100 Ohms for some reason?
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
