Question

select the correct term to complete the statement:
if the drift velocity of electrons increased, the current would ______
○ increase
○ decrease
○ stay the same

Explanation:

The formula for electric current is \( I = nqAv_d \), where \( n \) is the number of charge carriers per unit volume, \( q \) is the charge of each carrier, \( A \) is the cross - sectional area of the conductor, and \( v_d \) is the drift velocity of the charge carriers (electrons in this case). From this formula, we can see that the current \( I \) is directly proportional to the drift velocity \( v_d \) (when \( n \), \( q \), and \( A \) are constant). So, if the drift velocity of electrons increases, the current will also increase.

Answer:

A. increase
