Exercise 27

Solve Problem, assuming that the source is an ideal current generator that supplies a direct current of 0.7 (A) out of terminal 1.
Problem:
Find the current and the heat dissipated in each of the five resistors in the network shown in Fig. if
R 1 =
R 2 = 20 ( ), R 3 = 30 ( ), R 4 = 8 ( ), R 5 = 100020( ),
and if the source is an ideal d-c voltage generator of 0.7 (V) with its positive polarity at terminal 1. What is the total resistance seen by the source at terminal pair 1-2
