(a)

Kirchhoff's laws are fundamental principles in electrical circuit analysis that govern the behavior of currents and voltages in a circuit. These laws are named after Gustav Kirchhoff, a German physicist who formulated them in the mid-19th century. The two main laws are:

1. Kirchhoff's Current Law (KCL): The KCL states that the algebraic sum of currents entering and leaving any junction (or node) in a circuit is zero. In other words, the total current flowing into a junction is equal to the total current flowing out of that junction. This law is based on the principle of conservation of charge. Mathematically, KCL can be expressed as:

This equation means that the sum of currents entering a junction is equal to the sum of currents leaving the junction. KCL is often used to determine unknown currents at junctions in a circuit.

2. Kirchhoff's Voltage Law (KVL): The KVL states that the sum of voltage drops and rises around any closed loop in a circuit is zero. In other words, the total voltage around a closed loop is equal to the sum of voltage drops and rises within that loop. This law is based on the principle of conservation of energy. Mathematically, KVL can be expressed as:

?V = 0

This equation means that the sum of voltage rises and drops in a closed loop is equal to zero. KVL is commonly used to determine unknown voltages or voltage drops across elements in a circuit.

By applying Kirchhoff's laws, along with other circuit analysis techniques such as Ohm's law and network theorems, it is possible to solve complex electrical circuits and analyze their behavior. These laws provide a foundation for circuit analysis and are essential tools for understanding and designing electrical systems.

To find the equation for the potential difference between points A and B in the given circuit, we need to analyze the circuit step by step.
Let's assume the potential at point A is VA and the potential at point B is VB.
