A Wheatstone bridge initially has resistances equal to R1 = 200Ω, R2 = 400Ω, R3=500Ω and R4=600Ω. For an input voltage of 5V, determine the output voltage by analysing this condition.
What is the bridge output if R1 changes to 250Ω?

Given:  

Initially, the resistance of a cobblestone bridge equals

voltage at input

The bridge's output is:

ACB is connected to a 5V supply.

(regular voltage division)

Similarly, at point D, the voltage is
