Yes, Uab = -Uba. Look at it as a KVL "walk" from one node to another. In one case you're "walking downhill", dropping overall in potential from +18V to 0V, and in the other case "walking uphill" from 0V to +18V.alexmath said:

Solving an electric circuits problem involves understanding the basic principles of electricity and circuits, such as Ohm's Law and Kirchhoff's Laws. You will also need to know how to calculate voltage, current, and resistance in series and parallel circuits. It is important to carefully analyze the problem, draw the circuit diagram, and use the appropriate equations to find the solution.
If you are stuck on an electric circuits problem, try breaking it down into smaller parts and solve them one by one. You can also try working backwards from the desired solution. It may also be helpful to review the basic concepts and equations related to electric circuits.
To check your answer for an electric circuits problem, you can use a multimeter to measure the voltage, current, and resistance at different points in the circuit and compare them to your calculated values. You can also use simulation software to create a virtual circuit and compare your results with the simulation.
Some common mistakes to avoid when solving an electric circuits problem include using incorrect equations, using the wrong units for measurements, and forgetting to include all components in the circuit. It is also important to double-check your calculations and make sure they are consistent with the given information.
Yes, there are often multiple ways to solve an electric circuits problem. You can use different methods, such as nodal analysis or mesh analysis, to simplify the circuit and find the solution. It is important to choose the method that is most efficient and accurate for the specific problem.
