SUMMARY
The discussion centers on calculating the energy used by a flashlight powered by two 1.5V batteries in series, resulting in a total voltage of 3.0V. The current draw is specified as 1.00 mA, and the flashlight operates for 2.0 minutes. Using the formula for energy (E = V * I * t), the energy consumed can be calculated in Joules.
