The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that if the potential difference (V) across two points is zero, then the current (I) between these two points should also be zero. - According to Ohm's Law, current is defined as \( I = \frac{V}{R} \), where \( R \) is the resistance. If \( V = 0 \), then \( I = \frac{0}{R} = 0 \) (assuming \( R \) is not zero). 2. **Analyzing the Reason**: - The reason provided states that the current passing through a resistor is given by \( I = \frac{V}{R} \). - This is indeed correct as per Ohm's Law. It tells us that the current through a resistor is directly proportional to the potential difference across it and inversely proportional to the resistance. 3. **Conclusion**: - Since both the assertion and the reason are true, and the reason correctly explains the assertion, we can conclude that both statements are valid. - Therefore, the answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion. ### Final Answer: Both the assertion and reason are true, and the reason is the correct explanation of the assertion. ---
