HELP PLEASE!!

Problem 22.02 The plate on the back of a certain computer scanner says that the unit draws 0.44A of current from a 120V, 60Hz line. Part A Find the root-mean-square current. Express your answer using two significant figures. Irms=0.3 A Part B Find the current amplitude. Express your answer using two significant figures. Imax= A Part C Find the average current. Express your answer using two significant figures. BarI= A Part D Find the average square of the current Express your answer using two significant figures. Bar I^2= A^2

Explanation / Answer

I rms = 0.44/sqrt(2)= 0.31 A

b) amplitude = 0.44 A

c) average = 0

d) average square = rms^2 = 0.31^2 = 0.0961
