A sinusoidal current $i=I \cos \omega t$ has an rms value $I_{\mathrm{rms}}=$2.10 A. (a) What is the current amplitude? (b) The current is passed through a full-wave rectifier circuit. What is the rectified
average current? (c) Which is larger: $I_{\text { ms or }} I_{\text { rav }} ?$ Explain, using graphs of $i^{2}$ and of the rectified current.
