Physics Tutorial: Combination Circuits

2021-11-28 · R eq = 1 / (0.333 Ω -1) R eq = 3.00 Ω. Based on this calculation, it can be said that the two branch resistors (R 2 and R 3) can be replaced by a single resistor with a resistance of 3 Ω. This 3 Ω resistor is in series with R 1 and R 4. Thus, the total resistance is. R tot = R 1 + 3 Ω + R 4 = 5 Ω + 3 Ω + 8 Ω.
