Voltage received by each bulb in a circuit

AI Thread Summary
In a circuit with multiple bulbs, the voltage received by each bulb depends on their arrangement, whether in series or parallel. When bulbs are connected in parallel, each bulb receives the full voltage supplied by the cells, which is 1V per cell. A suggestion was made to redraw the circuit diagram to clarify the connections, ensuring each bulb has its own two wires. One participant initially miscalculated the voltage distribution but gained clarity through discussion. The conversation emphasizes the importance of circuit layout in determining voltage across components.

What is your idea? Have you tried redrawing the diagram, such that each bulb has it's own two wires, attaching somewhere to the line with the cells?

I have have tried drawing 2 circuits for each battery, where two bulbs are in one parallel section and one bulb in the other.
I got the answer wrong,
 
A.T, thank you for your help, I think I understand the question now!

Hi A.T., is the top middle point at ##1V##? I see it's also connected to ground..
 
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...
