For the post office box arrangement to determine the value of 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 an experiment to determine an unknown resistance, a 100 cm long resistance 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
What is the value of unknown resistance R, if galvonometer shows null deflection in the given meter bridge set up?
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.
If not current flows through the galvanometer the find the value of unknown resistance X. Assume that resistance per unit length of wire AB is 0.2 Omega//cm . then also calculate total current given by battery.
Passage : Post office is useful to measure the value of unknown resistance correctly upto 2nd decimal place. It is based on Wheatstone bridge. Systematic diagrams of post office box are shown in the above figures. Each of the arms AB and BC contains three resistance of 10 Omega, 100 Omega and 1000 Omega . These arms are generally known as ratio arms. With the help of these resistance, we can introduce resistance P in arm AB and Resistance Q in arm BC. The resistance arm AD is complete resistance box containing resistance from 1 Omega "to" 5000 Omega . In this arm, we can introduced resistance R by taking out plugs of suitable values. The unknown resistance X is connected in fourth arm CD. These four arms actually form Wheatstone bridge shown in figure. For balanced conditions, no deflection is formed in galvanometer. At balanced condition PX= QR , X= (QR)/( P) While measuring surface tension of water using capillary rise method, height of the lower meniscus from free surface of water is 3cm while inner radius of capillary tubne is found to be 0.5cm. Then compute surface tension of water using this data. [Take contact angle between glass and water as 0° and g=9.8 ms^(-2) ]
