Question

AL SDEMATIC A plot of the power delivered to Re in Fig. 9.120 for a range of values for R extending from 0 to 30 n FIG. 9.122 plot generated appears as a listing at the bottom left of the W/RL) Before leaving the subject, we should mention that the pou can be determined in more ways than one from the Add Trac box. For example, first enter a minus sign because of the resu rent direction through the resistor, and then select V2(RL) fol the multiplication of IRL). The following expression will appe Trace Expression box: V2(RL) I(RL), which is an expression the basic power format of P V I Click OK, and the sam curve of Fig. 9.122 will appear. Other quantities, such as the across the load and the current through the load, can be plotted RL by simply following the sequence Trace-Delete All Traces- Add Trace-V1(RL) or I(RL). PROBLEMS 120 SECTION 9.2 Superposition Theorem 1. a. Using superposition, find the current through resistor of the network of Fig, 9.123. b. Find the power delivered to R. for each source. c Find the power delivered to Ri using the total cu through R d. Does superposition apply to power effects? Expla R6n 10 V FIG. 9.123 Problem L
