AI Thread Summary
To calculate the voltages and currents at points A, B, and C, the superposition theorem may not be effective due to the presence of a voltage source that prevents a closed circuit when current sources are removed. Instead, applying Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL) is recommended for accurate analysis. The voltage at point B and the currents at points A and C can be determined using these laws. These methods will provide a systematic approach to solving the circuit's parameters. Utilizing KCL and KVL will lead to the correct calculations for the voltages and currents at the specified points.

I'm trying to determine the voltages and currents at points A, B and C of the attached drawing. I tried it by using the superposition theorm. Only this doesn't work with the voltage source, because the current can't "run" through the circuit, because the currentsources are than deleted, and there is no closed circuit.
My question is: what is the right way to calculate the voltages and current at the 3 points. And what are voltages and currents at the 3 points?

Thanks for your help!

Welcome to Physics Forums.

To start, can you say what the voltage at B is, as well as the currents at A and C?

For the rest, try using Kirchhoff's Current Law and Voltage Law (KCL and KVL) for the circuit.

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}...
