SUMMARY
The discussion focuses on calculating the internal resistance of a circuit using the formula (Rt * Rint) / (Rt + Rint). The user initially assumed the total resistance (Rt) to be 26.7 kΩ by summing two resistors in series but encountered discrepancies with the textbook answer. Participants emphasized the importance of correctly positioning the digital multimeter (DMM) in the circuit and calculating the current and voltage across the appropriate resistor to determine the internal resistance accurately.
