To calculate the total resistance (Rt) in this circuit, we need to consider the resistors in both series and parallel combinations.

First, we can simplify R2 and R3 as they are in series:

R23 = R2 + R3 R23 = 2Ω + 5Ω R23 = 7Ω

Now, we have the following resistors in the circuit: R1 = 4Ω, R23 = 7Ω, and R4 = 10Ω. These resistors are in parallel, so we can calculate the total resistance as follows:

1/Rt = 1/R1 + 1/R23 + 1/R4 1/Rt = 1/4Ω + 1/7Ω + 1/10Ω 1/Rt = 0.25 + 0.1429 + 0.1 1/Rt = 0.4929 Rt = 1 / 0.4929 Rt ≈ 2.03Ω

Therefore, the total resistance in the circuit is approximately 2.03Ω.
