7. For the bridge circuit given, Vsupply = 70V, and R₁= 2002, R₂=4022, R3=37.50, R4=509 and R5= 1000. For Delta to wye conversion, the following assumption is made Ra is between R₁ and R₂; R₁ is between R₂ and R5; Rc is between R5 and R₁ • What the voltage V5? 5 Volts 10 Volts 25 Volts 15 Volts Vsupply 100

circuit is in balance for values R2 = R3 and R1 = 1/(20wC1) a) calculate Cx loss factor b) which component is ideal to replace R1-C1 for the bridge to stay in balance, why?
