In a Wheatstone bridge PQRS, a galvanometer is connected among Q and S and a voltage source between P and R.
An unknown resistor Rx is connected among P and Q.
When the bridge is balanced, the resistance among Q and R is 200Ω, that between R and S is 10Ω and that among S and P is 150Ω.
Calculate the value of Rx .
