Ideal DC circuit comparison
Lower R?
Or raise V?
Reach the same current by two paths, then inspect what happens to power before carrying the analogy any further.
Run the circuit comparison.
Same flow does not mean the same electrical burden.
At fixed voltage, halving resistance doubles current and power.
At fixed resistance, doubling voltage doubles current but quadruples power.
Real circuits add heat, tolerances, source limits, nonlinear loads, and safety constraints.
