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 ...

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 ...

Measuring current is always a nuisance because you have to break the circuit to put the measuring device in series with the circuit. That problem never goes away. Still, any high-end digital ...

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 ...

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 ...

WHEN using high-frequency heating methods the thermo-electric measurement of temperature is difficult because of stray high-frequency current picked up in the measuring circuit.

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 ...

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

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 ...
