URGENT URGENT URGENT
calculate the rms value of alternating current shown

Answer 1

The graph and the waveform of the current is not visible.

However, the way to calculate the RMS value of AC current is:
 1. find the mean position.
 2. find the extreme position - peak value.
  3  amplitude I₀  = peak value - mean value
   4  rms value of current = I_rms = I₀ / √2
