You're a retarded idiot.

Note also that you have no clue as to how inductive circuits behave.

I was playing with using old car generators to power my go-carts and
playing with automotive coils and rebuilding lawn mower engines before
you were even born.

I know what a flux field collapse spike is. Your father must have
zapped you upside da haed a few times. You act like you have had to much
electro-shock therapy in your life.


Which of the following two statements is correct.

First statement:
"The coil's flux collapses and creates a spike. The diode clamping
that spike does NOT slow the spring loaded return time of the plate
which is attached to the contact(s) as it pulls away from the solenoid
core end face.
So, the answer is NO. The magnetic field is collapsing, as in NOT
"holding in" the relay any longer. The plate begins to pull away as
soon as the power is removed, and the clamping diode does nothing to
slow that process."

Second statement:
"Note also that the diode is also the best at suppressing the spike.
Note also that UNsupressed is the only way to get it fast. ALL the
other methods slow it."

I repeat, you are an ignorant berk.

The relay will drop out only when the coil current falls below the
hold-in current. Any suppression method allows the coil current to
gradually decay to zero and must lengthen the drop-out time.
