If V is the potential difference between the ends of conductor and l is the current through it, then ohm's law states that

Options

A. `V prop l`
B. `V prop (1)/(l)`
C. `V prop l^(2)`
D. `V prop l^(0 )`

Answer

To solve the question regarding Ohm's Law, we will follow these steps:

### Step 1: Understand the Concept of Ohm's Law
Ohm's Law is a fundamental principle in electrical engineering and physics that describes the relationship between voltage (V), current (I), and resistance (R) in a conductor.

### Step 2: State Ohm's Law
According to Ohm's Law, the potential difference (V) across a conductor is directly proportional to the current (I) flowing through it, provided the temperature and material of the conductor remain constant.

### Step 3: Write the Mathematical Expression
The mathematical expression for Ohm's Law can be written as:
\[ V = I \cdot R \]
where:
- \( V \) is the potential difference (voltage) across the conductor,
- \( I \) is the current flowing through the conductor,
- \( R \) is the resistance of the conductor.

### Step 4: Conclude the Statement
From the above expression, we can conclude that:
- If the resistance (R) is constant, an increase in voltage (V) will result in a proportional increase in current (I), and vice versa.

### Final Answer
Ohm's Law states that the potential difference (V) across a conductor is directly proportional to the current (I) flowing through it, which can be expressed as:
\[ V \propto I \]
or
\[ V = I \cdot R \]
