An electric device draws 3.0 A from a 110 V, 50 Hz line. For this device, what are the following: (a) the average current (b) the average of the square of the current (c) the peak current.
Added by Amanda G.
Step 1
0 A. So, the average current is $\boxed{3.0\,\text{A}}$. (b) For a sinusoidal current, the average of the square of the current is given by half of the square of the peak current. Show more…
