If you mostly deal with DC current, you might not think much of root mean square or RMS measurements. Sure, you’ve seen meters that have “true RMS” settings, but what does it mean? If you don’t know — ...

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 ...

The RMS value of a time dependent voltage or current is based on the simple concept of equality of power dissipation; however, its theoretical calculation or instrument implementation may not be easy.

Some applications require the monitoring of power applied to a system. Microchip Technology addressed this need with the MCP39F511A, a highly integrated, single-phase power-monitoring IC intended for ...
