Relaxation time is a crucial concept in various fields of science and engineering, such as physics, chemistry, and materials science. This article aims to explain the relaxation time formula and its significance in different contexts.
Relaxation time refers to the time taken for a system to return to equilibrium or its initial state after being disturbed. The concept is used to describe the behavior of systems that undergo a change in their properties, such as the decay of an excited state in atoms or the response of a material to mechanical stress. The relaxation time formula i...
The relaxation time formula is typically represented as: τ = 1 / (k * T) In this equation, τ (tau) represents the relaxation time, k is a proportionality constant that depends on the specific process being studied, and Tis the temperature of the system. The formula illustrates that relaxation time is inversely proportional to temperature.

Let’s consider a simple example to demonstrate the calculation of relaxation time in the context of electrical conductivity. In this scenario, we will use the Drude model, which calculates the relaxation time of electrons in a metal. The relaxation time formula for the Drude model is given as: τ = m / (n * e² * μ) In this equation: 1. mis the mass ...
Learn how relaxation time, collision time and mean free path are defined and related in electronics. Find out how relaxation time governs the establishment of equilibrium in electron gas and how it affects the conductivity and mobility of electrons.
The relaxation time is a measure of the time it takes for one object in the system (the "test star") to be significantly perturbed by other objects in the system (the "field stars"). It is most commonly defined as the time for the test star's velocity to change by of order itself.
Learn how to define relaxation time as the time gap between two successive electron collisions in a conductor, and how it is related to the drift velocity of free electrons. Use this relation to derive the expression for the electrical resistivity of the material.
