Question
**Bridge Circuit Analysis for Delta to Wye Conversion**

In the given bridge circuit:

- Supply Voltage, \( V_{\text{Supply}} = 70V \)
- Resistances:  
  - \( R_1 = 20\Omega \) 
  - \( R_2 = 40\Omega \) 
  - \( R_3 = 37.5\Omega \)
  - \( R_4 = 50\Omega \) 
  - \( R_5 = 100\Omega \)

For a Delta to Wye conversion, the following assumptions are made:
- \( R_a \) is between \( R_1 \) and \( R_2 \)
- \( R_b \) is between \( R_2 \) and \( R_5 \)
- \( R_c \) is between \( R_5 \) and \( R_1 \)

**Problem Statement:**

- What is the value of \( R_b \)?

**Options:**
- \( 25\Omega \)
- \( 12.5\Omega \)
- \( 4\Omega \)
- \( 10\Omega \)

**Diagram Explanation:**

The diagram illustrates a bridge circuit configuration with resistors labeled as \( R_1 \), \( R_2 \), \( R_3 \), \( R_4 \), and \( R_5 \). The voltage supply (\( V_{\text{Supply}} \)) connects the bridge network on its left side. 

This exercise involves using the Delta to Wye transformation principles to determine the value of resistor \( R_b \), positioned between \( R_2 \) and \( R_5 \) in the equivalent circuit.
