Transcribed Image Text:**Example 2: (a) Calculate the equivalent resistance of the circuit below (Fig. B).**
**Diagram Explanation:**
- **Figure B** shows an electrical circuit.
- It includes a voltage source and four resistors labeled as \( R_A, R_B, R_C, \) and \( R_D \).
- The resistances are:
- \( R_A = 20\Omega \)
- \( R_B = 10\Omega \)
- \( R_C = 10\Omega \)
- \( R_D = 20\Omega \)
- The resistors \( R_B \) and \( R_C \) are connected in parallel. This parallel combination is in series with \( R_A \) and \( R_D \), which are connected in series.
