    Answer:

    Resistance of the gas is given as

    R = 2.34 \times 10^{15} Ohm

    Explanation:

    As we know that number of electrons per second is

    \frac{N}{t} = 8 \times 10^6

    now we have

    i = \frac{N}{t} e

    i = 8 \times 10^6 (1.6 \times 10^{-19})

    i = 1.28 \times 10^{-12}

    now we have

    R = \frac{V}{i}

    R = \frac{3000}{1.28 \times 10^{-12}}

    R = 2.34 \times 10^{15} Ohm
