Q59PE When an unknown resistance聽Rxis... [FREE SOLUTION]

Chapter 21: Q59PE (page 777)

When an unknown resistance $R_{x}$ is placed in a Wheatstone bridge, it is possible to balance the bridge by adjusting $R_{3}$ to be $2500 惟$ . What is $R_{x}$ if $\frac{R_{2}}{R_{1}} = 0.625$ ?

Short Answer

Expert verified

The value for the unknown resistance in the Wheatstone bridge is $R_{x} = 1562.5 惟$ .

Step by step solution

Concept Introduction

A Wheatstone bridge is an electrical circuit that balances two legs of a bridge circuit, one of which includes the unknown component, to measure an unknown electrical resistance. The circuit's main advantage is its capacity to deliver exceedingly exact readings.

Information Provided

The Wheatstone bridge with a resistance: $R_{3} = 2500 惟$
The values for $\frac{R_{2}}{R_{1}} = 0.625 .$ .

Calculation for Resistance

The formula for calculating the resistance is 鈥�

$R_{x} = R_{3} \frac{R_{2}}{R_{1}} = (2500 惟) 脳 0.625 = 1562.5 惟$

Therefore, the value for resistance is $R_{x} = 1562.5 惟$ .
