Four Resistances P,Q,R,X formed a wheat stone bridge. The bridge is balanced when R=1002. If P and Q are inter changed the bridge balance for 1212 The value of x is 4. 1) 1002 2) 2002 3) 3002 4) 1102 5. In the circuit shown in the figure, the value of Resistance X,when potential difference between the points B andD is zero will be 21Ω 8Ω 32 18Ω D 1) 92 2) 82 3) 62 4) 42 Four Resistances P,Q,R,X formed a wheat stone bridge.
