When measuring electrical current, the goal is to insert an ammeter in series with the circuit so that the current measured by the ammeter is identical to the current flowing through the circuit. In ...

If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

The simple circuit design in Figure 1 lets you measure all components of a current flowing in a dc servo motor. The rectified output of the circuit uses ground as a reference, so you can measure the ...

Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current ...

Current measurement components and methods must provide an accurate output signal as well as preventing damage to the associated printed circuit board. Current sensing is used to perform two essential ...

Inductors and transformers serve key roles in switch-mode power supplies. Ensuring they perform as expected requires thorough in-circuit measurements performed under operating conditions. Here’s what ...

So you have power circuit breakers at your facility, and they seem to be just fine, sitting there quietly doing their job. What you may not realize is that even though your circuit breakers are ...

Siemens Power Transmission and Distribution has expanded its range of products with the new high-current and generator circuit breaker 3AH37 Siemens Power Transmission and Distribution has introduced ...

ROHM’s ultra-compact complementary metal–oxide–semiconductor (CMOS) operational amplifier (op amp) TLR1901GXZ achieves the ...
