Establish the condition required to make the current through Ze in Figure 1 zero (i.e. For the voltage Vx to equal Vy).
The Attempt at a Solution
I'm not sure if I'm on the right line here, hopefully someone can point me in the right direction if it's wrong...
If Zb and Zc were the same value then the voltage drop across them would be equal, likewise Za and Zd would also have to be the same value to have voltage Vx equal to Vy. In this condition there will be no current flowing through Ze.
Is my attempt correct or at least on the right path?
Thanks in advance
