**ions**which reach the anode transfer their excess electrons to thatelectrode and the positive

**ions**are neutralized by the electrons they receive fromthe cathode. These

**ions**may react with the material of the electrodes or they may...

The effective value of d becomes much smaller as a positive-

develops and hence the electron current is increased. The value of V, which is

approximately the breakdown potential, is in general not greatly altered.
