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 ...

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 ...

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 ...

In this PowerUp CircuitLab episode, we explore current measurement techniques on a hair dryer with both resistive and inductive components. In this PowerUp CircuitLab episode, we explore 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 ...

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 ...

An ohmmeter can be used to measure the resistance of a resistor Alternatively, the resistor can be placed in a circuit and the voltage across it, and the current in the resistor can be measured. Ohm’s ...

The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.
