\begin{abstract}
This paper looks in detail a the generic `resistor'
as a component in safety critical designs and
how its potential failure modes are taken into
account in various safety design standards.
A `networked resistor' equivalent to single
resistors is proposed for highly safety critical measurement sensitive
designs, as it has two not three failure modes to consider.
