To determine the amount of charge that passes through the cross-section of a wire carrying a current of 0.015 A over a period of 10 seconds, we can use the relationship between current ($I$), charge ($Q$), and time ($t$). The formula that relates these quantities is:

$Q = I \times t$

where:

• $Q$ is the charge in coulombs (C),
• $I$ is the current in amperes (A),
• $t$ is the time in seconds (s).

Given:

• $I = 0.015$ A,
• $t = 10$ s,

we can calculate $Q$ as follows:

$Q = 0.015 \, \text{A} \times 10 \, \text{s}$ $Q = 0.15 \, \text{C}$

Therefore, the charge that passes through the cross-section of the wire every 10 seconds is $0.15$ coulombs.
