Final answer:
To determine the values of resistors r1, r2, and r3 in a series circuit, add their values together. If the values given are 0.5 Ω, 7.5 Ω, and 11 Ω, the total resistance would be 19 Ω.
Step-by-step explanation:
The student has asked to determine the values of resistors (r1, r2, and r3) in a series circuit. Since the circuit is a series circuit, the total resistance is the sum of all individual resistances. Given the resistance values of 0, 5 Ω, 7, 5 Ω, and 11 Ω, we add them up to find the total resistance.
Here are the steps to calculate the total resistance:
- Add the first resistance value, 0, 5 Ω, to the second value, 7, 5 Ω.
- Next, add the third resistance value, 11 Ω, to the sum from step 1.
- The final sum is the total resistance of the circuit.
Note that the commas in the given resistance values might be representing decimals or thousands separators; clarification is required to provide the exact sum. If treated as decimal separators, the values are 0.5 Ω, 7.5 Ω, and 11 Ω respectively.
If we total these resistance values, we get:
Total resistance (Rt) = r1 + r2 + r3 = 0.5 Ω + 7.5 Ω + 11 Ω = 19 Ω
