A circuit is constructed with six resistors and two batteries as shown. The battery voltages are V1 = 18 V and V2 = 12 V. The positive terminals are indicated with a + sign, The values for the resistors are: R1 = R5 = 64 Ω, R2 = R6 = 156 Ω R3 = 53 Ω, and R4 = 64 Ω. The positive directions for the currents I1, I2 and I3 are indicated by the directions of the arrows.
What is I3, the current that flows through the resistor R3? A positive value for the current is defined to be in the direction of the arrow. (Hint: Will including the right loop tell you anything useful for this question? No.
What is I2, the current that flows through the resistor R2? A positive value for the current is defined to be in the direction of the arrow.
What is I1, the current that flows through the resistor R1? A positive value for the current is defined to be in the direction of the arrow.
