Power (mW)500.00 mW
Power Dissipated vs Voltage Across Component
Formel
## Power Dissipation **P = V x I** Also: **P = I^2 x R** and **P = V^2 / R**. All forms are equivalent via Ohm's Law.
Lösungsbeispiel
5 V across a component at 100 mA.
- 01P = 5 x 0.1 = 0.5 W = 500 mW
- 02Ensure component is rated above 0.5 W.
Häufig Gestellte Fragen
Why does it matter?
Excess heat damages components and reduces reliability.
How to reduce dissipation?
Lower voltage, reduce current, or use a more efficient component.
Safe margin?
Derate by 50%: use a 0.5 W resistor for 0.25 W dissipation.
