For hydrogen electrode:
{tex}{H^ + } + {e^ - } \to \frac{1}{2}{H_2}{/tex}
Applying Nernst equation:
{tex}E = {E^{0}} - \frac{{0.0591}}{n}\log \frac{1}{{\left[ {{H^ + }} \right]}}{/tex}
{tex} = 0 - \frac{{0.0591}}{1}\log \frac{1}{{{{10}^{ - 10}}}}{/tex} [pH = 10 means {tex}\left[ {{H^ + }} \right]{/tex}
{tex} = {10^{ - 10}}M{/tex}
{tex} = - 0.0591 \times 10 = - 0.591V{/tex}

A corona discharge: Corona discharge is a phenomenon of charge transfer by ionization of a fluid (may also include gases) surrounding a charged conductor, it is seen as a blue light between two sharp point electrodes kept at high potential difference. When a conductor having high charge density is placed in a fluid (or air) the medium becomes conducting because of the high electric intensity and leads to ionization of the atoms.

The process of meeting of negative and positive charges to release huge amount of energy is called electric discharge.

Yogita Ingle 6 years, 2 months ago

Electric discharge is defined as the process of the release and transfer of electricity in an applied electric field through any possible medium. Usually, electric discharge is made to occur through a gas or the atmospheric air.

Lavanya ❤️? 6 years, 2 months ago

Charge on 6 uf capacitor will be equal to product of capacitance and potential difference. = 6uf×2v =12 u coulombs there fore charge on 12uf capacitor will be equal 12 u coulombs. And potential difference across it will be = capacitance = charge ÷ potential difference therefore, v = q÷c v= 12 u c ÷ 12 uf v = 1 volt therefore total potential difference is = 2v + 1v = 3v

In physics a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero. Applying an electric field adds to this random motion a small net flow in one direction; this is the drift. Drift velocity is proportional to current. In a resistive material it is also proportional to the magnitude of an external electric field. Thus Ohm's law can be explained in terms of drift velocity. The law's most elementary expression is: {\displaystyle u=\mu E,} u=\mu E, where u is drift velocity, μ is the material's electron mobility, and E is the electric field. In the MKS system these quantities' units are m/s, m2/(V·s), and V/m, respectively
