Question

Find \( V_s \) and \( R_s \) for the following circuit 

• A. \( V_s = 10 \, \text{V} \) and \( R_s = 5 \, \Omega \) respectively
• B. \( V_s = 20 \, \text{V} \) and \( R_s = 5 \, \Omega \) respectively
• C. \( V_s = 10 \, \text{V} \) and \( R_s = 9 \, \Omega \) respectively
• D. \( V_s = 20 \, \text{V} \) and \( R_s = 9 \, \Omega \) respectively

Hint:

Use Kirchhoff's laws to calculate the voltage and resistance in simple circuits.

Answer 1

The Correct Option is A

- From the given circuit, we use Kirchhoff's Voltage Law (KVL) to calculate the voltage and resistance. 
- After performing the necessary calculations, we find that \( V_s = 10 \, \text{V} \) and \( R_s = 5 \, \Omega \). 

Conclusion: The correct values of \( V_s \) and \( R_s \) are as shown in option (a).
