AI Generated Solution

To derive the balance condition in a Wheatstone bridge using Kirchhoff's rules, we will follow these steps: ### Step 1: Understand the Wheatstone Bridge Configuration A Wheatstone bridge consists of four resistors arranged in a diamond shape. Let the resistors be: - P (connected between points A and B) - Q (connected between points B and C) - R (connected between points D and A) - S (connected between points D and C) ...

Balanced Wheatstone Bridge

(a) State Kirchhoff's rules for an electirc network. Using Kirchhoff's rules, obtain the balance condition in terms of the resistances of four arms of Wheatstone bridge. (b) In the meter bridge experimental set up, shown in the figure, the null point 'D' is obtained at a distance of 40 cm from end A of the meter bridge wire. If a resistance of 10 Omega is connected in series with R_(1), null point is obtained at AD = 60 cm. Calculate the values of R_(1) and R_(2).

Figure 6.64 shows a balanced wheatstone bridge.

Wheatstone bridge can be used

In the balanced condition , the values of the resistance of the fourarms of a Wheatstone bridge are shown in the figure below. The resistance R_(3) has temperature coefficinet 0.0004""^(@)C^(-1) . If the temperature of R_(3) increased by 100^(@) C , the voltage developed between S and T will be _____volt.
