When measuring the resistance of a component using a standard digital multimeter, which ports should you connect the test leads to?
A
VΩ and 10A
B
mA and 10A
C
COM and mA
D
COM and VΩ
Verified step by step guidance1
Understand that when measuring resistance with a digital multimeter, you need to use the ports designed for voltage, resistance, and continuity measurements.
Identify the common port (COM), which is the reference or ground connection for the test leads.
Locate the port labeled VΩ, which is used for measuring voltage, resistance (Ω), and sometimes continuity.
Recognize that the ports labeled mA and 10A are used for measuring current, not resistance, so they are not appropriate for resistance measurements.
Therefore, to measure resistance, connect the test leads to the COM port and the VΩ port on the multimeter.
