When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Relays are used to connect, or disconnect, ring generators to-and-from telephone lines. If the two points are at different potentials, there are high-current transients at the moment of contact. This ...

OVERCURRENT DETECTOR - the circuit introduced here is a simple and fast-responding overcurrent detector for protection of low-voltage applications. Unlike dedicated hot-swap controllers that impose a ...

Current measurement can serve as a means for managing system thermal performance. 1 One of the main reasons for managing system thermals via current measurement is to prevent system damage via fault ...
