II. High pressure.
III. High p.d.
IV. Low p.d.
Which combination of the above is true of the conduction of electricity through gases?
I and IV only
I and III only
II and IV only
II and III only
Explicació
Electricity conduction through gases is usually done under low pressure (I) and high voltage (III). Thus OPTION B is correct.
