Correct Answer

A

Explanation

NP/NS=VP/VS;N/1000 =120/1200N=100 turnsThe conduction of electricity through gases typically involves the following combinations:

I. Low pressure
IV. Low p.d. (pressure difference)

In gaseous conductors, such as in gas discharge tubes or plasmas, electricity often flows more readily at low pressure, and a low pressure difference (voltage) is required to initiate and sustain the conduction. High pressure and high pressure difference (voltage) are not typically associated with the conduction of electricity through gases.
