Final answer:
The total resistance of the series circuit with resistors R1 (0.5 ohms) and R2 (1.5 ohms) is 2 ohms.
Step-by-step explanation:
In a series circuit, the total resistance is equal to the sum of the resistance values of the resistors connected in series. In this case, we have two resistors, R1 with a resistance of 0.5 ohms and R2 with a resistance of 1.5 ohms, wired in series. To find the total resistance, we simply add the resistance values:
Total resistance = R1 + R2 = 0.5 ohms + 1.5 ohms = 2 ohms
Therefore, the total resistance in the circuit is 2 ohms.
