Monitoring the current taken by a mains-powered appliance can be a challenge, particularly if the application demands an inexpensive solution that must provide galvanic isolation for user safety.

The better the analog front-end for measuring battery current, the more accurately you'll be able to gauge the remaining run-time for your battery-backup system. Here's a discrete front-end design ...

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 ...
