The circuit was developed to produce a continuity tester with a low resistance mainly for checking the connections between soldered joints. Operational Amplifier (Op-Amp) – a DC coupled high gain ...

This is a simple and easy designed circuit which is used to test the continuity. We know that continuity tester will used to test whether there is continuity or connection between two components. Here ...

Almost every meter you find today will have a continuity tester. Connect the probes and it will beep if there is a short and won’t if there isn’t. But where is the short? That’s another problem when ...

A. F. BUBNS, in an article on testing of the crossbar system of telephony (Bell Lab. Rec., 20, No. 9 ; May, 1942), points out that in dialling systems a talking connexion is established through a ...
