Question

Additional question: An LED operates at a current of 40 mA, with a forward voltage of 2.4 V. You construct the series circuit shown in Fig. 2.43 to power the LED using two 1.5 V batteries, each with a capacity of 2000 mAh. Determine the required value of the resistor and how long the circuit will operate before the batteries run out of energy.
