what actually happens is that when the pressure is normal very weak current which can just be measured through quadrant electrometer is there... when applied pressure is lowered then no. of ions remains same but as pressure is decresed the electrons present in anions leave the ion and start moving freely and thus then electricity is conducted with the help of electron and as the mass of electron is less than any ion so it will more efficiently and thus current will be more...... rest concept depends on current as u ppl knows.......
