What is the total resistance of three 12-ohm resistors connected in series?

Explanation:
In a series circuit, resistances simply add up because the same current flows through each component. For three 12-ohm resistors in series, the total resistance is 12 + 12 + 12 = 36 ohms. This is the resistance the current encounters as it passes through all components, with voltages dividing according to each resistor. The other numbers would come from different scenarios: 24 ohms would be two resistors in series, not three; 12 ohms would imply only one resistor is affecting the circuit; 48 ohms would require four resistors in series.
