Solution:

Show me the final answer↓

We can use the following equation to figure out the charge transferred.

q=it

(Where q is charge, i is the current, and t is the time)

 

Substitute the values we know.

q=(2.5\times 10^4)(20\times 10^{-6})

q=0.5 C

 

Final Answer:

q=0.5 C

 

This question can be found in Fundamentals of Physics, 10th edition, chapter 21, question 4.
