Current. Too little of it, and you can’t get where you’re going, too much and your hardware’s on fire. In many projects, it’s desirable to know just how much current is being drawn, and even more ...

Current often is derived from the voltage drop measured across a shunt of known value. However, as the paper states, “It is common practice for current shunts to be calibrated at a single current ...

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the ...

Measuring AC current (220-V mains RMS current) is not as simple as measuring DC current. In DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the ...

At electronica 2024, Tektronix launched its new power instrumentation, including an RF isolated current probe and three-channel bidirectional power supply, targeting industries that demand greater ...

Question: How do you measure inductor current? Answer: Switched-mode power supplies commonly use inductors to temporarily store energy. In the evaluation of these power supplies, it’s often useful to ...
