This Design Idea shows how to use a 63¢ (Q=1) microprocessor reset voltage detector IC in a relay coil drive circuit to greatly reduce the coil’s hold-in current. When asked to estimate the coil ...

The CTRC Rogowski coil current transformers are flexible, rope-like current sensors that can be connected around conductors. With their flexible design, the CTRC transformers are perfect for large bus ...

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...

A nondestructive testing technology called eddy current array (ECA) is capable of driving numerous eddy current coils that are positioned next to one another in the same probe assembly. In the probe, ...

The MAX4172 substitutes itself as a current amplifier for the shunt normally associated with a moving coil meter. The moving coil meter can be used even when the meter current is a fraction of the ...

There are two main types of electrical current that flow through your home: Alternating and direct. The vast majority of devices around you are powered by alternating current. By allowing electrons to ...
