Ohm my


One of the most common mistakes I hear techs make is confusing Zero ohms with infinite ohms.

If there is a perfect path it would have zero ohms (which isn’t actually possible unless you happen to be testing a superconductor).

If there is no path, the circuit has infinite ohms.

Often when I ask what ohm reading a tech is getting they will say “none”…

None could easily mean zero or infinite so it’s important to clarify.

Once again.

Zero ohms = shorted / closed / directly connected

Infinite ohms = open/ no path
