    Load Voltage
AI Thread Summary
The discussion revolves around a load voltage problem where the correct answer is identified as -3. Participants highlight the importance of considering both I1 and I2 currents when calculating the final voltage across the resistor. There is an emphasis on maintaining consistent units throughout the calculations. Acknowledgment of an error in the initial approach is noted, leading to clarification on the method needed to find the fault. The conversation underscores the necessity of thorough analysis in electrical problems.

It is hard to read your approach.
You just consider I2 to calculate the final voltage, but there is also I1 flowing through the resistor. And you should use units in a consistent way.
 
You are right. My mistake!

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}...
