The equations under conditions of balance for a bridge measuring resistance R1, and inductance L1 of a choke coil are

In order to achieve convergence of balance

Detailed Solution: Question 3

The bridge circuit for the given balance condition indicates that of a Maxwell’s inductance capacitance bridge as shown below.

For sliding balance, R4 and C4 will be varied since they are not common in the equations of R1, and L1.
in order to achieve convergence to balance point, R4 and C4 will be varied since they are in the same arm of the bridge.

In measurement of resistance by “Carey Foster bridge” no error is introduced due to

Detailed Solution: Question 4

“Carey Foster slide wire bridge” is a special type of bridge circuit which is used for the measurement of medium resistance by comparing with a standard known resistance. This bridge circuit will give no error due to connecting lead resistances, thermoelectric emfs and contact resistances.
