RL Time Constant
τ = L_ind / R
What it says
How quickly current builds in an inductor through a resistance.
Symbols
| Symbol | Quantity | Dimension |
|---|---|---|
τ | Time constant (s) | T |
L_ind | Inductance (H) | M L^2 T^-2 I^-2 |
R | Resistance (Ω) | M L^2 T^-3 I^-2 |
Work it out
Enter what you know. No account needed.
Fill in all but one: L_ind, R, τ are all empty.
