HOW?
How does closing a relay wether it is a hot closure or not produce a
transient in anode current?
I always thought anode current (other than bias current) was produce by a
driving signal. Hot switching is not good, but I don't think it is a
cause of anode current transients. I fail to see the connection (no pun
intended!).
