Which statements are true? a) At any junction point in a circuit, the sum of all the currents entering the junction must equal the sum of all the currents leaving the junction. b) The sum of the changes in potential around any closed loop of a circuit must equal zero. c) Kirchoff's junction rule is based on the conservation of energy. d) Kirchoff's loop rule is based on the conservation of charge.

The figure below shows five resistors and two batteries connected in a circuit. What are the currents I1, I2, and I3? (Consider the following values:  R1 = 1.20 Ω, R2 = 2.16 Ω, R3 = 3.19 Ω, R4 = 4.18 Ω, R5 = 6.18 Ω.  Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign. Indicate the direction with the sign of your answer.)I1=?I2=?I3=?
