How Do You Calculate Total Resistance in a Diagonal Battery and Resistor Setup?

AI Thread Summary
To calculate the total resistance in a diagonal battery and resistor setup, the two resistors (4 ohms and 6 ohms) are in parallel. The formula used is (1/4 + 1/6)^-1, resulting in a total resistance of 2.4 ohms. Visualizing the circuit as an equivalent circuit with straight wires can help clarify the connections. The shape and length of the wires do not affect the resistance calculation. Understanding this parallel configuration simplifies the problem significantly.

I tried finding this same problem somewhere in the forums here but I couldn't find a similar one, its getting the best of me! I have a problem with a square and a line going diagonal from corner to corner, with a 1.5v battery on the diagonal and on the top side a 4ohm resistor and 6ohm resistor on the other side. So the battery intersects the corner with a resistor on either side of the corner. Would it just be two in parallel so (1/4 + 1/6)^-1 = 2.4ohms? I cannot figure it out, help please!

A lead can be as sort as you like. Both terminals of those resistors are connected through the wires, and the shape and length of the wires does not matter. You are right, the resistors are in parallel, and the resultant is 2.4 ohms.

if you get confused by seeing the shapes, don't worry. try drawing an equivalent circuit, keeping the terminals same, using straight wires. you will see easily that its a parallel connection.
 
Ah, i see. That's whatwas holding me up. Thanks guys!
 
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 hanged 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...
