10.1 Circuits, charge and current

Question 2

A telemetry sensor in an oceanographic research buoy is programmed to draw a continuous current of 15 mA during an active data-transmission cycle.

Calculate the total quantity of charge that flows through the sensor's telemetry circuit during a transmission cycle lasting $minutes4.0\text{ minutes}$ .

State the unit of charge with your answer.

Use the equation:

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