$\cdot$ The plate on the back of a certain computer scanner says that the unit draws 0.34 A of current from a $120 \mathrm{V}, 60$ Hz line. Find (a) the root-mean-square current, (b) the current ampli- tude, (c) the average current, and (d) the average square of the current.
A television set draws an rms current of $2.50 \mathrm{A}$ from a $60-\mathrm{Hz}$ power line. Find (a) the average current, (b) the average of the square of the current, and (c) the amplitude of the current.
An electric motor is being powered with a voltage amplitude of $310 \mathrm{~V}$ at $60.0 \mathrm{~Hz}$. The motor draws a current amplitude of $10.0 \mathrm{~A}$. Find (a) the root-mean-square voltage, (b) the root-mean-square current, and (c) the average power consumed by the motor.
