CASE ANALYSIS
Scenario
A 120V AC household branch supplies three identical 60W incandescent bulbs, each modeled as a 240Ω resistor in parallel across line and neutral.
Key decisions
- Model each bulb as a 240Ω resistor (P=V^2/R)
- Place all three resistors in parallel across the same live bus and neutral
- Include a 15A fuse on the live feed for overcurrent protection
When to reuse this
Reuse for any parallel resistive load grouping where multiple identical loads share a common voltage source.
