If R2 is set to 15 ohms, the total resistance will

Explanation:
When you change a resistor in a network, the total resistance changes based on how the resistors are connected. If the resistors are in parallel, the total resistance is governed by 1/Rt = 1/R1 + 1/R2. Increasing R2 makes its branch less conductive (1/R2 gets smaller), so the sum of conductances decreases and Rt increases. If the resistors are in series, the total is simply Rt = R1 + R2, so raising R2 directly raises the total as well. Therefore, setting R2 to 15 ohms raises the total resistance.
