Question: What is the Thevenin equivalent voltage (Vth) across terminals A and B if V1 = 10V and R1 = 5Ω, R2 = 10Ω in series?

Options:

Correct Answer: 10V

Solution:

In a series circuit, the Thevenin voltage is the same as the source voltage, so Vth = V1 = 10V.

What is the Thevenin equivalent voltage (Vth) across terminals A and B if V1 = 10V and R1 = 5Ω, R2 = 10Ω in series?

Correct Answer: 10V

Step 1: Identify the components in the circuit. We have a voltage source V1 = 10V and two resistors R1 = 5Ω and R2 = 10Ω connected in series.
Step 2: Understand that in a series circuit, the total voltage across the terminals is equal to the voltage of the source.
Step 3: Since we are looking for the Thevenin equivalent voltage (Vth) across terminals A and B, we note that Vth is the same as the source voltage when there are no other loads connected.
Step 4: Therefore, we can conclude that Vth = V1 = 10V.
