Four resistances of respectively in cyclic order to form Wheatstone's network. The resistance that is to be connected in parallel with the resistance of to balance the network is ___________.
Option: 1 10
Option: 2 5
Option: 3 15
Option: 4 20
For balanced Wheatstone bridge
As
So using
We get
let we connected x-ohms in parallel to 10-ohm resistance
i.e
we get
So the answer will be 10.
