Let V = 12V, R1 = 140, R2 = 80, R3 = 402, R4 = 60 and R5 = 14 (20 points) R3 R1 13 14 0 Wv 12 R4 Loop 1 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 I2 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 Q4) An outer metal ring of radius 3m, surrounds an inner metal ring of radius 2 m, as shown in the figure. The current in the outer ring is moving in the counterclockwise direction and it increased from 3A to 6A within 0.5 s. a) Find the magnetic fields (B1 and B2) at the center of the rings when the outer current is 3A and when the outer current is 6A b) Find the change in the magnetic flux at the center, due to the change in current c) Using Faraday's Law find the induced emf in the inner circular loop d) Using Lenz's find the direction of the induced current in the inner ring
