A Wheatstone bridge is used to measure resistance. Show that in this circuit if the current flowing
Question:
Show that in this circuit if the current flowing through rg is zero then r4 = r2r3=r1. (To operate the device, put the unknown resistance at r4. At rg is a meter that shows the current. We vary the three resistances r1, r2, and r3-typically they each have a calibrated knob-until the current in the middle reads 0. Then the equation gives the value of r4.)
