A Electron drift velocity in a gas discharge

AI Thread Summary
The drift velocity of free electrons in gas discharge is likely higher than that of electrons in a conductor when both are subjected to the same voltage. This is due to the lighter mass of gas discharge electrons, allowing them to accelerate more effectively. In gas discharges, electrons experience less resistance compared to those in conductors. Consequently, the dynamics of electron movement differ significantly between these two environments. Understanding these differences is crucial for applications involving gas discharges and conductive materials.

Is the drift velocity of gas' free electrons during the gas discharge higher than the one of the conductor's electron fliquid while the voltages supplied to these two substances are the same?

Welcome to PF.

The lightest particle in the gas discharge will be electrons. It is probable that electrons will be accelerated to higher velocities than ions in the gas discharge, or electrons in the conductors.

Thread ''splain this hydrostatic paradox in tiny words'

This is (ostensibly) not a trick shot or video*. The scale was balanced before any blue water was added. 550mL of blue water was added to the left side. only 60mL of water needed to be added to the right side to re-balance the scale. Apparently, the scale will balance when the height of the two columns is equal. The left side of the scale only feels the weight of the column above the lower "tail" of the funnel (i.e. 60mL). So where does the weight of the remaining (550-60=) 490mL go...

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...
