← TechnologyWhat electrical behavior causes 'current hogging' in parallel LEDs?
A)Negative thermal coefficient reducing resistance✓
B)Capacitive reactance increasing effective resistance
C)Avalanche breakdown affecting multiple junctions
D)Reverse recovery creating spurious conduction
💡 Explanation
Runaway occurs because the negative temperature coefficient of LEDs decreases resistance with increasing temperature; therefore more current flows preferentially through those LEDs, rather than distributing current evenly and avoiding hotspots with lower current.
