sources of noise
When the load changes very rapidly, as when a relay contact
is closed, the inductance in the hook- up wire and in the
power supply output will cause a spike to appear at the
load. The spike is a function of the rate of change of the
load current. When very rapid changes in load are expected,
a capacitor with a low series resistance, in parallel with the
power supply, and close to the load is the best way to
minimize these voltage spikes.
