one of my friend has a problem with zener. in his circuit, he put a zener(5.6) in series with 20V and 220K resistor.
it works fine but after a while the voltage across the zener drops below 3V when he change the zener the same problem has happened. would you please give a reason about this behavior of the circuit?
