In the shown circuit, no cell and no current flows. The outside current is zero everywhere. Inside the branches, the outside current is 1 ampere. Since the resistor has one amperage, the resistor in the branch of the resistor has 1 ampere. If the branch of the cell is an open circuit, it will have no current, and then the top branch will have one ampere. When adding the top branch to the one ampere of outside current, the total amperes = 1 + 1 = 2 amperes. The outside current and inside amperes are equal.
The path of the area current is the sum of the path of the branch current and the path of the main. The branch current is the sum of the paths of the two branches. Therefore, the total current is the sum of the two paths. When subtracting the outside current from the total current, the net current is the two paths, which is the same amperes. The current in the two branches is the same.
The branch current is everywhere the same. The branch resistance is above the resistor, and the branch resistance is below it. However, the branch resistance must be the same above and below the resistor. The resistance of the branch is the summation of the resistances above and below the resistor. Therefore, the branch resistance is 1 ampere. When subtracting the current in the branches from the current of the resistor, the net current is the sum of the branch current and the current in the resistor. When adding the branch current to the current in the resistor, the total current is the sum of the branch current and the current in the resistor. Therefore, the branch current is 1 ampere. The resistance of the branch is 1 ampere. The resistor has 1 ampere of current. A sum of the two is 2 amperes.
In this circuit, the branch current is the same in this circuit, which will always be lesser. When the branches are parallel, the current is the same above and below the resistor. The resistance is identical above and below the resistor. d2c66b5586
