I. Low pressure.
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?
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
解释
Electricity conduction through gases is usually done under low pressure (I) and high voltage (III). Thus OPTION B is correct.
