Ohm's Law specifically defines the relationship between voltage, current, and resistance in an electrical circuit. It states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. This relationship can be mathematically represented by the formula V = I × R.

Understanding this law is fundamental in electricity and electronics, as it allows one to analyze and calculate the behavior of electrical circuits. It applies to many practical applications where one must understand how changes in voltage and resistance will affect the current flow.

In contrast, Kirchhoff’s voltage law deals with the sum of the electrical potential differences (voltages) around any closed network and is not primarily focused on the relationship of voltage, current, and resistance. Faraday's law relates to electromagnetic induction and is about how electric current is generated by changing magnetic fields. Newton's third law is a principle of motion in physics that concerns action and reaction forces, not electrical relationships. Thus, Ohm's Law is the essential concept here that succinctly expresses the interaction between voltage, current, and resistance.
