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.
