E PART B . 1. a) RIGHT (The resistance of the parallel combination of R 2 and R 3 is smaller than the resistance of R 2 alone, so more current will flow.) b) LEFT (Since less current flows through R 1 in the left circuit, there is a smaller potential drop across it, and consequently, a larger potential drop across R 2 .) c) LESS THAN THE CURRENT THROUGH R 1 (The sum of the currents through R 2 and R 3 must equal the current through R 1 .) 2. a) The magnitude of ∫ ⋅ s B d = μ (3.0 A) = 12 π ×10-7 T·m = 3.8 ×10-6 T·m b) NEGATIVE (The direction of integration about the enclosed wire is opposite to the direction of the magnetic field produced by that wire.) c) ATTRACTIVE (The two wires carry currents in the same direction, so they attract.) NAME PART C . 1. a) enclosed q A d E = ∫ ⋅ ε q enclosed = 0, so ∫ ⋅ A d E ε = 0 ¯¯¯¯¯¯¯¯¯¯¯¯ b) enclosed...
