The bridge circuit shown in Fig. 1 is energized from a 24 V dc source. The bridge is balanced when R1 = 500 Ω, R2 = 1000 Ω, and R3 = 750 Ω.

a) What is the value of Rx?

---

b) Flow much current (in milliampcres) does the dc source supply?

---

c) Which resistor in the circuit absorbs the most power? How much power does it absorb?

---

d) Which resistor absorbs the least power? How much power does it absorb?
