I want to know about the workings of an electric neon tester. For example when I insert the tester in one terminal of the AC socket, the light glows but when I insert into another terminal it doesn’t – why?
As taught to me in college, for the first half-cycle one terminal (say T1) of the AC socket is positive while the other (say T2) is negative and for the second half cycle terminal T2 is +ve and T1 is -ve and our body offers resistance as well as capacitance to complete the circuit and cause the light to glow.
Then according to this logic the tester should glow when inserted in any of the two terminals but it doesn’t,why?
