Find the current through each resistor using the rules for series and parallel resistors

Consider the circuit shown in the figure. Suppose the four resistors in this circuit have the values R1 = 12 Ω , R2 = 7.1 Ω , R3 = 7.1 Ω , and R4 = 13 Ω , and that the emf of the battery is E = 18 V .Part AFind 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 =___________ APart BFind the current through each resistor using Kirchhoff’s rules.Express your answers using two significant figures separated by commas.I1,I2,I3,I4 =____________ Awん 2 3 4
