Question - Identifying Electrical Laws by Formula

The provided equation is \( I \propto \frac{V}{R} \), where \( I \) is the current, \( V \) is the voltage, and \( R \) is the resistance. This formula demonstrates the direct relationship between the current flowing through a conductor and the voltage across it, while being inversely proportional to the resistance of the conductor.

This relationship is described by Ohm's Law, which 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. Ohm's Law can be written in equation form as:

Given the options provided:

• Hukum Lenz (Lenz's Law) is related to electromagnetism and describes the direction of an induced current in a conductor due to a changing magnetic field.
• Hukum Ohm (Ohm's Law) is the principle we are discussing, which defines the relationship between voltage, current, and resistance.
• Hukum Kirchoff Arus (Kirchhoff's Current Law), also known as Kirchhoff's first law, deals with the conservation of charge at a junction; it states that the total current entering a junction is equal to the total current leaving the junction.
• Hukum Kirchoff Voltan (Kirchhoff's Voltage Law), also known as Kirchhoff's second law, deals with the conservation of energy in electrical circuits; it states that the total sum of electrical potential differences around any closed network is zero.

Based on the explanation above, the correct answer to the equation \( I \propto \frac{V}{R} \) corresponds to:

Therefore, the correct option is B. Hukum Ohm.
