Plasma Electron Relaxation Time Calculator

Calculate the electron relaxation time using: $$ \tau_e = \frac{3 \sqrt{m_e}\,(k_B\, T_e)^{3/2}}{4 \sqrt{2}\,\pi\, n_e\, e^4 \ln\Lambda} $$

* Ensure all inputs are in SI units: $T_e$ in K, $n_e$ in m$^{-3}$, and $\ln\Lambda$ as a dimensionless number.

Step 1: Enter Plasma Parameters

Electron Temperature, $T_e$ (K):

e.g., 10,000 K

Electron Density, $n_e$ (m$^{-3}$):

e.g., 1×10¹⁸ m⁻³

Coulomb Logarithm, $\ln\Lambda$:

e.g., 10 (dimensionless)
