SUMMARY
The discussion focuses on calculating the potential difference across a resistor in an RC circuit with a resistance of 1M Ohm, a capacitance of 1 Micro Farad, and a voltage source of 30 V. The correct formula to use is V = E (1 - e^(-t/RC)). After 10 seconds, the expected voltage across the resistor should be 4V, indicating that the capacitor is charging and the voltage across the resistor is decreasing. The confusion arises from the interpretation of the charging process, where the voltage across the resistor approaches zero as the capacitor fully charges.
