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 ...

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 ...

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 ...

You often need to measure currentduring circuit design and debugging.You can perform that task bybreaking a path, inserting a shunt resistor,measuring its voltage, and convertingthe voltage to current ...

Monitoring the current taken by a mains-powered appliance can be a challenge. Here's an approach centered on Hall-effect sensors and current-sense transformers, which afford the galvanic isolation ...

What do a Rogowski coil, a magnetic core, and a hall effect sensor have in common? They are all ways you can make oscilloscope probes that measure current. If you think of a scope as a voltage ...

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 ...

According to ROHM, its ultra-compact TLR1901GXZ CMOS op amp is the industry’s lowest operating circuit current. The op amp is built to be used as a measurement-sensing amplifier in space-constrained ...

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 Semiconductor today announced the development of the TLR1901GXZ, an ultra-compact CMOS operational amplifier (op amp) that achieves the industry’s lowest operating circuit current. Optimized for ...
