For the post office box arrangement to determine the value od unknown resistance, the unknown resistance should be connected between, (a) B and C (b) C and D (c) A and D (d) B_(1) and C_(1) . .

Shown in figure is a Post Office box. In order to calculate the value of external resistance, it should be connected between

In the arrangement of resistances shown in figure. Find the value of unknown resistance X if the potential difference between B and D is zero.

In an experiment to determine an unknown resistance, a 100 cm long rets tance wire is used. The unknown resistance is kept in the left gap and a known resistance is put into the right gap. The scale to measure length has a least count 1 mm. The null point B is obtained at 40.0 cm from the left gap. We shell determine the percentage error in the computation of unknown resistance.

In the circuit shown here, what is the value of the unknown resistor R so that the total resistance of the circuit between points P and Q is also equal to R

Using Kirchoff's rules determine the value of unknown resistance R in the circuit so that no current flows through 4 Omega resistance. Also find the potential difference between A and D.
