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 ...

When you need a continuity tester at the bench, what do you reach for? Probably your multimeter, right? It may surprise you to know that the continuity tester in the meter isn’t all that sensitive, ...

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 ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...
