Electric Circuits? It’s All About Nodes, Branches, and Loops - EEP
2016年4月23日 · A loop is a closed path formed by starting at a node, passing through a set of nodes, and returning to the starting node without passing through any node more than once. A loop is said to be independent if it contains at least one branch which is not a part of any other independent loop.
Kirchhoff's circuit laws - Wikipedia
The sum of all the voltages around a loop is equal to zero. v 1 + v 2 + v 3 + v 4 = 0. This law, also called Kirchhoff's second law, or Kirchhoff's loop rule, states the following: The directed sum of the potential differences (voltages) around any closed loop is zero.
Nodes, Branches and Loops of a Circuit | Electrical4U
2024年6月26日 · Loops in Electric Circuit. An electric circuit has multiple nodes. If you start at one node and travel through a set of nodes, returning to the starting node without crossing any intermediate node twice, you have completed a loop in the circuit. Loop is any closed path in the circuit formed by branches.
10.4: Kirchhoff's Rules - Physics LibreTexts
In this section, we elaborate on the use of Kirchhoff’s rules to analyze more complex circuits. For example, the circuit in Figure 10.4.1 is known as a multi-loop circuit, which consists of junctions. A junction, also known as a node, is a connection of three or more wires.

2017年10月12日 · A circuit MUST be a loop. When the loop is closed, current flows through the load. When the loop is open, the circuit is turned-off. Maybe you can assume that the voltage is the "force" which push the charges to flow in the loop. The current is that flow by unit of time. Without loop, there isn't current.

2018年5月7日 · An independent loop contains at least one branch that doesn't belong to another loop. So using your two loops, ABC and BC as examples: ABC contains branch 10V/5 Ohm that isn't in BC. BC contains the 3 Ohm which isn't in ABC, therefore they are independent.
