45%

An electrochemical cell used in a blood glucose monitor operates with a constant current of 15 mA during a single test cycle.

Calculate the total charge flow, in coulombs, through the sensor during a test cycle lasting $minutes8.5\text{ minutes}$ .

Use the equation:

\text{charge flow} = \text{current} \times \text{time}

\times t
