According to Kirchhoff’s Loop Rulea)The absolute sum of changes ...
Kirchhoff’s loop rule is based on the principle of conservation of energy. The work done in transporting a charge in a closed loop is zero. The algebraic sum ( since potential differences can be both positive and negative) of potential differences around any closed loop is always zero.

According to Kirchhoff’s Loop Rulea)The absolute sum of changes ...
Explanation:
Kirchhoff's Loop Rule, also known as Kirchhoff's Voltage Law (KVL), states that the algebraic sum of changes in potential around any closed loop in an electrical circuit must be zero.
Understanding Kirchhoff's Loop Rule:
When current flows through a closed loop in a circuit, it will encounter various components such as resistors, capacitors, and inductors. Each component will cause a change in potential (voltage) as the current passes through it.
Key Point:
The potential difference across a resistor is given by Ohm's Law, V = IR, where V is the potential difference, I is the current, and R is the resistance.
Explanation of the Options:
a) The absolute sum of changes in potential around any closed loop must be zero.
This statement is incorrect because the sum of changes in potential can be positive or negative, depending on the direction of the current and the nature of the components.
b) The algebraic sum of changes in potential around any closed loop must be negative.
This statement is also incorrect because the sum of changes in potential can be positive or negative, depending on the direction of the current and the nature of the components.
c) The algebraic sum of changes in potential around any closed loop must be positive.
This statement is incorrect as well because the sum of changes in potential can be positive or negative, depending on the direction of the current and the nature of the components.
d) The algebraic sum of changes in potential around any closed loop must be zero.
This statement is correct. According to Kirchhoff's Loop Rule, the algebraic sum of changes in potential around any closed loop in an electrical circuit must be zero. This means that the sum of the potential differences across all the components in the loop must add up to zero. This rule is based on the conservation of energy principle.
Conclusion:
Kirchhoff's Loop Rule states that the algebraic sum of changes in potential around any closed loop in an electrical circuit must be zero. This rule is fundamental in analyzing and solving complex electrical circuits.
