Example Three resistors are connected as shown R1 is 40 ohm, R2 is 96 ohm, and R3 is 24 ohm. If the battery has an EMF of 74 volts, determine the current flowing in R3. Answer: 1/R parallel = 1/R2 + 1/R3 = 1/96 + 1/24 = 5/96 Rp = 96/5 = 19,2 ohm R total = R1 + Rp = 40 + 19,2 = 59,2 ohm I = V/R = 74/59,2 = 1,25 A I at R3 = V/R = 74/24 = 3,08 A
