Question

"The electrical discharge through the gases could be observed only at very low pressures and very high voltage." Why is it so?

Answer 1

THE EXPERIMENT YOU ARE TAKING ABOUT IS HELD UP WHEN THE SCIENTIST SEE THUNDERBOLT FROM CLOUD, THE POSSIBILITY OF CONDUCTIVITY OF ELECTRICITY BY GASES ARISES FROM THERE
THAT IS WHY THEY CONDUCT EXPERIMENT AT SAME CONDITION BUT THEY CANNOT PRODUCE MORE THAN 10,000 VOLT SO THEY DECREASE THE PRESSURE
