In The Art of Electronics 3rd, it mentionmentions:

Resistors are used in power circuits to reduce voltages by dissipating power, to measure currents, and to discharge capacitors after power is removed.

I'm not sure what power circuits are, but I found a link (https://c03.apogee.net/mvc/home/hes/land/el?utilityname=imea&spc=foe&id=4703#:~Fundamentals of Electricity:text=A%20power%20circuit%20is%20defined,since%20they%20serve%20different%20purposes Types of Circuits - Power Circuits) that mentions:

Most lighting and receptacle outlet circuits in a house are power circuits since they only provide power to devices when the devices operate

This suggests that the typical 110V110 V and 220V220 V circuits used in homes, as well as the 380V380 V used in industry, are all power circuits. However, if you were to connect a resistor in series with these 110V110 V, 220V220 V, or 380V380 V circuits to step down the voltage, it would likely burn out the resistor. I’ve never seen this method of voltage reduction before.

Does "power circuits" refer to circuits with 110V, 220V, or 380V?
