Equivalent Resistance of Circuit System

AI Thread Summary
To solve the equivalent resistance problem, the 200 ohm and 300 ohm resistors can be grouped in parallel, while the 400 ohm and 80 ohm resistors form another parallel group. After calculating the equivalent resistance for each parallel group, these two results can be combined in series to find the total equivalent resistance of the circuit. This approach aligns with the principles of series and parallel circuits. Understanding how to identify and group resistors correctly is crucial for solving such problems effectively.

I'm having trouble with this problem. Any advice would be appreciated. I know I can't group all resistors together in one loop, but I'm not sure where to draw my loops.

Should I choose the 200 ohm and 300 ohm for one parallel and the 400 ohm and 80 ohm for the other parallel?

I have a general understanding of series/parallel circuits, but this one is throwing me.

Thanks again,

-Alex

You can make a single resistor with this one. The 200 and 300 ohm resistors are in parallel as are the 400 and 80 ohm resistors. The two equivalent resistors are then in series.
 
Thank you analogdesign! I'm glad I was on the right track. =)
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
