Consider the circuit shown in the figure (Figure 1). Suppose the four resistors in this circuit have the values R1 = 13 ̐, R2 = 6.9 ̐, R3 = 7.1 ̐, and R4 = 10 ̐, and that the emf of the battery is ̕ = 15 V. You may want to review (Pages 748-751). Part A Find the current through each resistor using the rules for series and parallel resistors. Express your answers using two significant figures separated by commas. I1, I2, I3, I4 Part B Find the current through each resistor using Kirchhoff's rules. Express your answers using two significant figures separated by commas. I1, I2, I3, I4
