    Battery Diagram
AI Thread Summary
The discussion clarifies the location of the battery in a circuit diagram where it is not explicitly shown. The top point labeled "36.0 V" represents the positive terminal of a 36.0 V battery, while the "ground" symbol indicates the negative terminal. It emphasizes that the circuit is completed through the battery, despite its absence in the visual representation. The user seeks guidance on how to redraw the circuit to include the battery explicitly. Overall, the conversation focuses on understanding circuit diagrams and the implicit connections within them.

Homework Statement


I'm having trouble figuring out where exactly the battery is and if it's connected in series or parallel when the diagrams are given like in the image below.

The book gives this description for the diagram. I don't really understand it.

The figure (Figure 1) employs a convention often used in circuit diagrams. The battery (or other power supply) is not shown explicitly. It is understood that the point at the top, labeled "36.0 V," is connected to the positive terminal of a 36.0 V battery having negligible internal resistance, and that the "ground" symbol at the bottom is connected to the negative terminal of the battery. The circuit is completed through the battery, even though it is not shown on the diagram.

In other words how can I redraw this to the more usual type of diagram, like the one below where the battery (or emf source) is shown explicitly (not the same circuit!).

Thanks.

Just like the description says...

Thanks you. That's more clear. :)
 
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}...
