Answer to Question #298650 in Electric Circuits for EDEN

Question

Laboratory report on determination of unknown resistance by potentialmeter

Answer 1

Voltage drop across S resistance

$V_s=IR$

Voltage drop across R resistor

$V_R=IS$

Now We know that

$\frac{V_R}{V_S}=\frac{R}{S}$

$R=\frac{V_R}{V_S}\times S$
