## Linear Regulator Efficiency
### Formula
**Efficiency = V_out / V_in x 100%**
Linear regulators are simple and low-noise but waste power as heat. Efficiency depends only on the voltage ratio, not on current. A 12V-to-5V linear regulator is only 42% efficient.

हल किया गया उदाहरण
12 V input, 5 V output, 1 A load.
- Efficiency = 5 / 12 x 100 = 41.7%
- Power delivered = 5 x 1 = 5 W
- Power wasted = (12 - 5) x 1 = 7 W
