I can’t say that I appreciate the details of Zener diodes, but conventional diodes allow the (electrical) current to flow in only one direction, hence the pun (involving water currents).

The use of current for talking about a phenomenon of electricity is, of course, a metaphorical extension of the water flow term.

    More likely, the father is fishing where the current is too high, overloading the Zener diode.
