SUMMARY
The discussion centers on the behavior of electric circuits, specifically regarding the path of least resistance when a switch is closed. When the switch is closed, current flows primarily through the closed switch, rendering the resistor between the cells effectively unused. The power dissipated by resistor X can be calculated using the equations p=IV, p=I^2R, and V=IR. Understanding these principles is crucial for analyzing circuit behavior in practical applications.
