When just two elements connect to form a node, t]!ey are said to be in seris. A closd path is a loop traced Problems Section 2.1 2.1 a) Is the interconnection of ideal sources in the cir-figlre P2.2 cuil in Fig. P2.1valid? Explain. b) Idenrify which sources aie developing and which sources are absorbing power. c) Verify that the total power developed in cuit equals the total power absorbed. d) Repeat (a)-(c), reversing the polarity 10V source. figure P2.1 If the interconnection ir Fig. P2.3 is valid, find rhe total power developed bythe voltage sources.If the interconnection is not valid, explain why. Figure P2,3 the cir-of the 2.3 3 0 v rhe the Tf rhe inlerconneclion in Fig. P2.2 is valid. find power developed by the current sources. If interconnection is not valid, explain why. 10v 2.2 10v...
