1. Read about the Root Mean Square a (RMS) and briey explain what it is. 2. The RMS current and voltage are 1/2 1m =(% ff dt) T Ems = (% f0 62 (it) 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 owing through R is assumed to be periodic with period T.) Compute these root mean squares, given that 8(t) = 3 + 1.5 cos(100t) volts and 1105) = 1 2 sin(100t %) amperes, 27r which corresponds to period T = W
