Assertion: Current is a scalar quantity.
Reason: Electric current arises due to continuous flow of charged particles or ions.

Options

A. If both Assertion `&` Reason are True `&` the Reason is a correct explanantion of the Assertion
B. If both Assertion `&` Reason True but Reason is not a correct explanation of the Assertion
C. If Assertion is True but the Reason is False
D. If both Assertion `&` Reason are False.

Answer

To analyze the assertion and reason provided in the question, let's break it down step by step.

### Step 1: Understanding the Assertion
The assertion states that "Current is a scalar quantity."

- **Explanation**: A scalar quantity is one that has only magnitude and no direction. In the case of electric current, it can be measured in amperes and is represented by a single value.

### Step 2: Understanding the Reason
The reason provided is "Electric current arises due to continuous flow of charged particles or ions."

- **Explanation**: Electric current (I) is defined as the rate of flow of electric charge (Q) through a conductor. Mathematically, it is expressed as:
\[ I = \frac{Q}{t} \]
where \(Q\) is the total charge flowing and \(t\) is the time taken. This definition indicates that current is indeed related to the motion of charged particles.

### Step 3: Analyzing the Relationship Between Assertion and Reason
Now, we need to determine if the reason supports the assertion.

- While both the assertion and the reason are true, the reason does not directly explain why current is a scalar quantity. The fact that current arises from the flow of charged particles does not inherently imply that it is a scalar. The assertion is based on the nature of current being additive in terms of magnitude, regardless of the direction of flow in different wires.

### Conclusion
Based on the analysis:
- The assertion is true: Current is a scalar quantity.
- The reason is true: Current arises due to the flow of charged particles.
- However, the reason does not explain the assertion.

Thus, the correct answer is that both the assertion and reason are true, but the reason does not explain the assertion.

### Final Answer
Both assertion and reason are true, but the reason does not explain the assertion.
