Question 12

A service record for a coastal water-quality buoy divides a sensor transmission into two stages. The charge counter records a total of 330 C for the transmission. During the opening 4.0 min, the current is 0.90 A. In the second stage, the current is steady at 0.30 A.

How long does the second stage last?
