Question : 10
Total: 26
Use Kirchhoff's rules to obtain conditions for the balance condition in a Wheatstone bridge.
Solution:
Obtaining condition for the balance Wheatstone bridge
− I 1 R 1 + 0 + I 2 R 2 = 0 ( I g = 0 )
For loop CBDC
− I 2 R 4 + 0 + I 1 R 3 = 0
⇒
=
From equation (ii)
=
∴
=
Applying Kirchoff's loop rule to closed loop ADBA
For loop CBDC
From equation (ii)
