[chbot] Robotics Group meeting, Monday 19 Nov 2018, 630pm, 5 Idris Road

[Mark Atherton]

Here is a start on snubbers : https://en.wikipedia.org/wiki/Snubber with 
link to https://en.wikipedia.org/wiki/Arc_suppression

For a mains application an X rated 0.1uF cap in series with 100R 1W 
resistor might be a good start (across contacts which need protection). 
This is for a slightly inductive load. Ambiguity indicates uncertainty, 
as in most cases...

Anyone got any better rules-of-thumb on the subject ?

-Mark
