Unformatted text preview: 3 R 5 R i s (t) Friday, August 26, 2011 Figure 1: Model circuit 1 American wire gauge, also known as the Brown & Sharpe wire gauge, is a standardized wire gauge system used since 1857 predominantly in the United States and Canada for the di-ameters of round, solid, nonferrous, electrically conducting wire. You can read more on this at http://en.wikipedia.org/wiki/American wire gauge 1 3 The power delivered to the source in the circuit of Figure 2 is 120 watts. (a) If I s = 2 A, determine the value of R . (b) Suppose now that R = 1 . Find I s . Figure 2: Model circuit 4 For the circuit in Figure 3, determine the current I out and the power P R 2 absorbed by the resistror R 2 , in terms of the current I in and the resistances R 1 and R 2 and the parameter .
