Question
![For the bridge circuit given, \( V_{supply} = 70V \), and \( R_1 = 20\Omega \), \( R_2=40\Omega \), \( R_3=37.5\Omega \), \( R_4=50\Omega \) and \( R_5=100\Omega \). For Delta to Wye conversion, the following assumption is 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 \( R_1 \).
**Question:**
What is the value of \( R_a \)?
**Choices:**
- \( 4\Omega \)
- \( 5\Omega \)
- \( 25\Omega \)
- \( 12.5\Omega \)
**Diagram Explanation:**
The diagram shows a bridge circuit with a power supply and resistors arranged in a specific configuration. The resistors are labeled \( R_1 \), \( R_2 \), \( R_3 \), \( R_4 \), and \( R_5 \), surrounding the power supply. The circuit layout is indicative of a bridge circuit, which often requires specific analysis techniques such as converting between Delta and Wye configurations for ease of calculation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0ab994c8-cff9-4fe5-97d8-93d0776b49d9%2F19e7c334-2796-4869-8ee5-73dfefb096fc%2Ftitz8nd_processed.png&w=3840&q=75)
