Question 22

An electrochemical sensor in an experimental glucose monitor is activated.

A charge of 0.084 C passes through the sensor in a time of 24 s.

Calculate the current in the sensor.

Use the equation:

current=chargetime \text{current} = \frac{\text{charge}}{\text{time}} current=timecharge​
