Ohm's law deals with the relation between :

Options

A. current and potential difference
B. capacity and charge
C. capacity and potential
D. charge and potential difference

Answer

**Step-by-Step Solution:**

1. **Understanding Ohm's Law**: Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points. This can be mathematically expressed as:
\[ V = I \cdot R \]
where R is the resistance of the conductor.

2. **Identifying the Relation**: From the equation \( V = I \cdot R \), we can see that Ohm's Law specifically relates current (I) and potential difference (V). The resistance (R) is a constant for a given conductor at a constant temperature.

3. **Analyzing the Options**:
- **Option 1**: Current and potential difference - This is correct as per Ohm's Law.
- **Option 2**: Capacity and charge - This is related to capacitors, not Ohm's Law.
- **Option 3**: Capacity and potential - This is also related to capacitors, not Ohm's Law.
- **Option 4**: Charge and potential difference - This does not relate to Ohm's Law.

4. **Conclusion**: The only correct option that describes the relationship defined by Ohm's Law is Option 1, which states that Ohm's Law deals with the relation between current and potential difference.

**Final Answer**: Option 1: Current and potential difference.
