Question: What is the Thevenin equivalent voltage across a 5Ω resistor in a circuit with a 10V source and a 10Ω resistor in series?
Options:
Correct Answer: 5V
Solution:
The voltage across the 5Ω resistor is half of the total voltage due to the voltage divider rule: V_th = 10V * (5Ω / (5Ω + 10Ω)) = 10V * (1/3) = 3.33V.
