You often need to measure current during circuit design and debugging. You can perform that task by breaking a path, inserting a shunt resistor, measuring its voltage, and converting the voltage to ...

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 ...

You would like a circuit to create a voltage that you can measure that is proportional to your load current. What circuit would you use? There are many circuits to measure current. One common approach ...

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 ...

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

How to effectively measure ultra-low bias current by recreating the measurement scheme from an app note. Measuring input capacitance and input current. Creating a better measurement environment. 3. Cp ...

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...

Inrush current effect is common in electric motors. Sometimes, in case of ill-designed electrical wiring systems, switching on the motor may activate the fuse. It is caused by the inrush current – ...
