These resistors are said to be in **parallel**, and
as before, it is possible to consider them as one single equivalent
resistor
*R*_{ eq} . To find this equivalent resistor, we exploit
the fact from charge conservation that
*I* = *I*_{1} + *I*_{2} . Using again Ohm's law (17.3), as well as the point
that the potential difference across *R*_{1} and *R*_{2} is the same,
we find this becomes
