In Wheatstone's network P = 2 Omega , Q = 2 Omega , R = 2 Omega and S = 3 Omega The resistance with which S is to shunted in order that the bridge may be balanced is

P, Q, R and S are four resistors of resistances 2, 2, 2 and 3 ohm respectively and are arranged to form a Wheatstone bridge network. Calculate the resistance with which the resistor S must be shunted in order that the bridge may be balanced.

In the Wheatstone's network given, P = 10 Omega, Q = 20 Omega, R = 15 Omega, S = 30 Omega .The current passing through the battery (of negligible internal resistance) is

In the Wheatstone’s network given below , P = 10 Omega, Q = 20 Omega, R = 15 Omega, S = 30 Omega . The current passing through the battery (of negligible internal resistance) is

If P, Q, R and S are the resistances in the arms of Wheatstone bridge, then the bridge is most sensitive, when :

ABCD forms the four arms of a Wheatstone's network. The arms AB, BC, CD, DA are of 10Omega, 15Omega, 25Omega and 20Omega respectively. The junctions B and D are connected to the ends of galvanometer of resistance 25Omega . If the source voltage is 5V, r = 0, then calculate the current in the galvanometer. Assume the branch currents across AB, BC, CD, DA and BD as i_(1),i_(3),-i_(4),-i_(2), and i_(g) respectively.

In the network shown in the figure, each of the resistance is equal to 2 Omega The resistance between the points A and B is

Given that R_1 = 2 Omega, R_2 = 3 Omega and R_3 = 6 Omega , combinations which will give an effective resistance of 4 Omega is
