When measuring circuit resistance with a DMM,what will the ohmmeter display when you place the test leads across an open portion of the circuit?
A) extremely low resistance
B) high resistance
C) OL
D) zero resistance
Circuit Resistance
The opposition to the flow of electric current within a circuit, measured in ohms, affecting the circuit's performance and power consumption.
DMM
Stands for Digital Multimeter, an electronic measuring instrument that combines several measurement functions in one unit, such as voltage, current, and resistance.
Ohmmeter
A device used to measure electrical resistance in units of ohms.

Final Answer :
C
Explanation :
An ohmmeter displays "OL" (overload) when the test leads are placed across an open portion of the circuit, indicating that the resistance is too high to measure or effectively infinite.
