Q3) Consider the circuit shown below with the resistors. Let V = 12V , R1 = 140, R2 = 80, R3 = 40 , R4 = 60 and R5 = 14 (20 points) R3 R1 13 14 9 12 11 Loop 1 R4 R2 +12V R5 14 0 a) Considering the individual resistors (R1, R2, R3, R4 and R5), find the equivalent resistance of the circuit. b) Find the total current supplied by the battery. Let's name this current as I1. c) Considering the given Loop 1 and using Kirchhoff's loop law, find the current 12 that flows through the R2 resistor. d) Using Kirchhoff's junction law at point P to find the current Is which flows through the resistors R3, R4 and R5
