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 =___________ A Part BFind the current through each resistor...
