Hello. I didn't count examples about plasma at school. Never yet. I'm trying it study on my own. I do not know what to do with a few examples. I do not know which formula to use. I give here one of them.

Calculate the resistivity of hydrogen plasma at 1 keV.

How can I do it?

How does one define resistivity, or it's reciprocal, conductivity?

"for a conducting medium we define the conductivity, σ, or resistivity, η, by . . . . "

1. What is the formula for calculating plasma density?

The formula for calculating plasma density is n = N/V, where n is the density, N is the number of particles, and V is the volume of the plasma.

2. How do you calculate the ionization energy of plasma?

The ionization energy of plasma can be calculated using the formula E = 13.6 * (Z^2 / n^2) eV, where E is the ionization energy, Z is the atomic number of the ion, and n is the principal quantum number of the electron.

3. What is the formula for calculating the Debye length of plasma?

The formula for calculating the Debye length of plasma is λ = √(ε*kT / n*q^2), where λ is the Debye length, ε is the permittivity of free space, k is the Boltzmann constant, T is the temperature, n is the plasma density, and q is the charge of the particle.

4. How do you determine the equilibrium pressure of a plasma?

The equilibrium pressure of a plasma can be determined using the formula P = nkT, where P is the pressure, n is the density, k is the Boltzmann constant, and T is the temperature.

5. What is the formula for calculating the plasma frequency?

The formula for calculating the plasma frequency is ωp = √(n*q^2 / ε0*m), where ωp is the plasma frequency, n is the density, q is the charge of the particle, ε0 is the permittivity of free space, and m is the mass of the particle.
