Power Dissipated vs Voltage Across Component
सूत्र
## 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.
हल किया गया उदाहरण
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.
अक्सर पूछे जाने वाले प्रश्न
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.
