What is the difference between series grounding and parallel grounding? Are the resistances the same
zhazha
Each one station should be connected shortly to ground, and at least separately. Each one wire can be broken incidentally and when you have like train cars connection to ground, you will receive all stations after disconnected. But if you use parallel grounding, only one station can produce damages for your products. It is the most important rule with making grounding. Second point of view is that for grounding it is not the most important resistance value, but impedance must be less than 1 ohm. Impedance is built not only from resistance but additionally with capacitance and inductance of the wire. Longer wire or smaller diameter of copper means higher impedance, and consider all bonding points (independent if screwed or soldered enough).
Thanks for the explanation,
