Question

The placement of resistors in a circuit is one factor that can determine the current passing through the resistor. You will be given three circuits, and for each circuit you will be asked to compare the current through the various resistors. In each of the circuits, all resistors are identical.

Rank below the three identical resistors (A, B, and C) in (Figure 1) on the basis of the current that flows through them.

Rank from largest to smallest. To rank items as equivalent, overlap them.

Answer 1

Answer 2

Concepts and reason

The concept used to solve this problem is Kirchhoff’s junction rule.

First, analyze the circuit diagram. Then, show the distribution of the amount of flow of current in the different parts of the circuit.

Fundamentals

Kirchhoff’s junction rule states that the algebraic sum of the current in any junction is zero.

Its mathematical expression can be expressed as follows,

$\sum I = 0$

Here, $I$ is the current.

Consider the circuit diagram as,

The rank of the resistors on the basis of the amount of current that flows in the circuit is as follows,

$A > B = C$

Ans:

The rank of the resistors on the basis of the amount of current that flows in the circuit is $A > B = C$ .
