| 4.2.2 | Using a multimeter to make resistance measurements

In this lab you will use a multimeter to measure the resistance and continuity of objects. The unit of measurement for both, is the ohm (Ω). Continuity refers to the level of resistance of a path. If a path is intentionally made into a low-resistance path, for use by two connected electrical devices, then the path has what is called continuity. If a path is unintentionally made into a low-resistance path, then it is called a short circuit.

With either measurement, the multimeter emits a high-pitched sound when it detects a low-resistance path. You will perform measurements on the following:

- CAT 5 cable
- terminated CAT 5 cable
- terminated coaxial cable
- telephone wire
- CAT 5 jacks
- switches
- wall outlets
