- Homework Statement
- How can I find the RMS value of a DC Current?

- Relevant Equations
- Vrms=Vpeak/(2)½

I had previously solved this using Root Mean Square method by integrating the value of voltage from t=0 to t=T/2 and then from t=T/2 to t=T.Answer was Vo/2½.Yesterday I found this question

if I followed the previous approach then:

5 volts is not even in the option. How can I find the DC component of an Output Sinusoidal Voltage?
