Cutoff Frequency vs Resistance
सूत्र
## RL Filter Cutoff **f_c = R / (2 x pi x L)** Time constant tau = L/R. An RL low-pass passes DC and attenuates high frequencies.
हल किया गया उदाहरण
R = 1k, L = 10 mH.
- 01L = 0.01 H
- 02f_c = 1000 / (2pi x 0.01) = 15,915.5 Hz
- 03tau = 0.01 / 1000 = 0.01 ms
अक्सर पूछे जाने वाले प्रश्न
RL vs RC filter?
Same rolloff rate (-20 dB/decade), but RL uses an inductor where RC uses a capacitor.
Why use RL over RC?
RL filters handle DC current better. Useful in power supply filtering.
Inductor disadvantages?
Inductors are larger, heavier, and more expensive than capacitors for most filter applications.
