Resistances R 1, R3 and R4, in an electrical circuit, are connected in series, then their equivalent resistance is:
R134 = R1 + R3 + R4 = 60 + 15 + 3 = 78 ohms.
Resistors R134 and R2 are connected in parallel, then the total resistance of the electrical circuit at points A and B is equal to: Rob = R134 * R2 / (R134 + R2) = 78 * 12 / (78 + 12) = 10.4 Ohm.
Answer: The total resistance of the electrical circuit is 10.4 ohms.
