Question: What is the Thevenin equivalent voltage if a circuit has a 10V source and a 2Ω resistor in series with a 4Ω load?

Options:

Correct Answer: 10V

Solution:

The Thevenin equivalent voltage is the open-circuit voltage across the load, which is the same as the source voltage in this case, 10V.

What is the Thevenin equivalent voltage if a circuit has a 10V source and a 2Ω resistor in series with a 4Ω load?

Correct Answer: 10V

Step 1: Identify the components in the circuit. We have a 10V voltage source, a 2Ω resistor, and a 4Ω load resistor.
Step 2: Understand that the Thevenin equivalent voltage is the voltage across the load resistor when it is open-circuited (not connected).
Step 3: In this case, since the load is connected in series with the 2Ω resistor and the 10V source, we need to find the voltage across the load.
Step 4: When the load is connected, the voltage across the load can be calculated using the voltage divider rule, but since we are looking for the open-circuit voltage, we can directly see that the entire voltage from the source appears across the load when it is open-circuited.
Step 5: Therefore, the Thevenin equivalent voltage is equal to the source voltage, which is 10V.
