Concept explainers

KVL and KCL

KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.

Sign Convention

Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.

i've already seen this solution. but regardless, i askedfor an explanation. i always have a big issue with understanding how to do nodal analysis in these type of circuits, how to name nodes and on what basis. how was the outgoing current 0-v0/3r and how do i identify it and in the incoming current. how to use voltage division rule here. so please annotate everything on the figure and help me understand all my above inquiries so i can understand how to solve these type of questions. thank you! please be extremely detailed and concise. also when can i and can i not use nodal analysis and voltae division rule
Hint:The wires here have zero resistance. Thus, for currents that travel along a wire that has no circuitelement, you can safely omit it and simplify the circuit. After, you can use the Kirchhoff's rules. Answer must be answer must be 0.99 A DOWNVOTE IF YOU DONT GET THIS ANSWER 0.99 A
