By measuring the resistance and flow of current, the tester can assess if there are any breaks or interruptions in the copper conductors.
we may use a LED in place of a bulb in a tester as LED glows even when there is a small electric current flow through it
A cable tester is used to test the electrical connections in a cable or other wired device. There are two ways to test for a connection: continuity test and resistance test. A cable tester can also test for a short by determining voltage.
