I need help calculating the RMS value of the fundamental component of source current. The electrical circuit is a fully controlled single phase rectifier bridge. In the lecture the value is:

This looks like homework..

Look on Youtube for “greatScott”. He has a great video on diodes and bridge rectifiers with all the revelent math and formula including RMS.

Calculating rms values is meaningful for repetitive (periodic) signals only.
The interval for integration is one period. Using symmetries the interval can be reduced to e.g. 1/2 period, 1/4 period or other fractions.
Your sketch doesn't show explicitly the periodicity. One may assume, I assume, that the signal repeats periodically, so the period would be ...(your's to find).
Using the symmetry of the signal you can reduce the interval to a smaller value.

By the way: while the text in your image is crisp, the sketch is rather blurry and veeery hard to read.
