Electronic – Is the given voltage Peak Voltage or RMS Voltage

accircuit analysis

In circuit diagram problems is the labelled voltage RMS voltage
or Peak Voltage ?

For example say in problems like this what is the usual convention?


I recently started learning about circuits and i'm in high school.I don't know if the question is suited for this site or not.But I thought of giving it a try.Do let me know if it's off-topic.

RMS should be assumed unless otherwise indicated. In this problem, "effective current" should be assumed to mean RMS current and the supply voltage should be assumed to be 200V RMS.
