The correct Answer is:
To analyze the statements provided in the question, we can break down the concepts of drift velocity and current in a conductor step by step. ### Step 1: Understand the relationship between current and drift velocity The current \( I \) flowing through a conductor is given by the formula: \[ I = N \cdot A \cdot e \cdot v_d \] where: - \( N \) = number of charge carriers per unit volume (free electrons) - \( A \) = cross-sectional area of the conductor - \( e \) = charge of an electron (approximately \( 1.6 \times 10^{-19} \) coulombs) - \( v_d \) = drift velocity of the charge carriers ### Step 2: Analyze Statement 1 Statement 1 claims that "as the drift velocity increases, the current flowing through the conductor decreases." From the equation, we see that if \( v_d \) (drift velocity) increases, then \( I \) (current) also increases, assuming \( N \), \( A \), and \( e \) remain constant. Therefore, Statement 1 is **false**. ### Step 3: Analyze Statement 2 Statement 2 states that "the current flowing through a conductor is directly proportional to drift velocity." From the same equation, we can see that current \( I \) is directly proportional to \( v_d \). Thus, if \( v_d \) increases, \( I \) also increases, confirming that Statement 2 is **true**. ### Conclusion - **Statement 1**: False - **Statement 2**: True Thus, the correct conclusion is that Statement 1 is false and Statement 2 is true. ### Final Answer - Statement 1 is false. - Statement 2 is true.
