(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In a fluorescent tube of diameter 3 cm, 10 *10^{18}electrons and 2.5 * 10^{18}positive ions (with a charge of +e) flow through a cross-sectional area each second. What is the current in the tube?

2. Relevant equations

Current is I = (delta Q)/(deta T)

3. The attempt at a solution

delta t is given as 1 second, but how do u calculate the change in charge given this information?
