the bridge circuit is energized from a 21 V dc source. the bridge is balanced when R1 = 800Ω, R2 =1200Ω, and R3 = 600Ω.
a) what is the value of Rx?
b) how much current(in milliamperes) does the dc source supply?
c) which resistor in the circuit absorbs the most power? how muchpower does it absorb?
d) which resistor absorbs the least power? how much power does it absorb?
