SUMMARY
The discussion centers on the behavior of resistors connected in parallel to an ideal voltage source. It establishes that an ideal voltage source maintains a constant voltage regardless of the current supplied, while a resistor in this configuration primarily generates heat without influencing the overall circuit analysis, unless it serves as a heat source. The conversation emphasizes the importance of drawing circuit diagrams to visualize voltage and current relationships effectively.

Because in those situations the resistor only generates heat. The resistor does not affect the way the rest of the circuit is analysed, unless the circuit is a heater or needs the heat source.
An ideal voltage source will maintain the ideal voltage, no matter how much current it must supply.
An ideal current source will provide sufficient voltage to maintain the ideal current, no matter how much voltage is dropped across the resistor.
