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

R1 =  R2 = 20 (Ω), R3 = 30 (Ω), R4= 8 (Ω), R5= 100020(Ω),

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?
