1. Read about the Root Mean Square & (RMS) and briefly explain what it is. 2. The RMS current and voltage are Irms = (+ So 2 at ) 1/2 Erms = (+ Sol e2 dt ) 1/2 where i and e are functions of t: i(t) and e(t), the current through and voltage across a pure resistance R. (The current flowing through R is assumed to be periodic with period T.) Compute these root mean squares, given that e(t) = 3+ 1.5 cos(100t) volts and i(t) =1 - 2 sin(100t - - ) amperes, which corresponds to period T = 100
