AI Thread Summary
The discussion revolves around a circuit calculation involving two resistors and two voltage sources. The user applied Kirchhoff's Voltage Law (KVL) to derive the current 'I' in the circuit, resulting in the equation I = (V2 - V1) / (2R). Despite following the correct steps, the user finds their answer does not match the provided solution. Other participants confirm that the calculations appear correct, prompting a request for clarification on what the "solution" states. The conversation highlights potential discrepancies in interpretation or additional factors not accounted for in the user's calculation.

I have attached the circuit of interest.
The 2 resistors of of resistance R. V1 and V2 are the voltage sources. 'I' is the current we're solving for.

Using KVL, we get:
-V1-R*I+V2-R*I=0
Rearranging:
V1-V2=-2R*I
(V2-V1)/(2R)=I


My answer doesn't seem to match the solutions. Am I missing something here?

Why? What does the "solution" say ?

(Looks good to me.)
 

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}...
