EMF of Unknown Cell using Potentiometer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Electromotive Force = (EMF of Unknown Cell using Potentiometer*Length)/Final Length
ε = (ε_'*L)/l₂
This formula uses 4 Variables

Variables Used

Electromotive Force - (Measured in Volt) - Electromotive force is the capability of the system to make the charge flow.
EMF of Unknown Cell using Potentiometer - (Measured in Volt) - EMF of Unknown Cell using Potentiometer is used to find emf of unknown cell and compare emf of two cells.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.
Final Length - (Measured in Meter) - Final Length is the measurement or extent of something from end to end.

STEP 1: Convert Input(s) to Base Unit

EMF of Unknown Cell using Potentiometer: 6 Volt --> 6 Volt No Conversion Required
Length: 1500 Millimeter --> 1.5 Meter (Check conversion here)
Final Length: 1200 Millimeter --> 1.2 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ε = (ε_'*L)/l₂ --> (6*1.5)/1.2

Evaluating ... ...

ε = 7.5

STEP 3: Convert Result to Output's Unit

7.5 Volt --> No Conversion Required

FINAL ANSWER

7.5 Volt <-- Electromotive Force

Potential Difference through Voltmeter

Go Electric Potential Difference = Electric Current through Galvanometer*Resistance+Electric Current through Galvanometer*Resistance through Galvanometer

Shunt in Ammeter

Go Shunt = Resistance through Galvanometer*(Electric Current through Galvanometer)/(Electric Current-Electric Current through Galvanometer)

Potential Gradient through Potentiometer

Go Potential Gradient = (Electric Potential Difference-Electric Potential Diff through other Terminal)/Length

EMF of Unknown Cell using Potentiometer

Go Electromotive Force = (EMF of Unknown Cell using Potentiometer*Length)/Final Length

Current in Potentiometer

Go Electric Current = (Potential Gradient*Length)/Resistance

Metre Bridge

Go Final Resistance = Resistance*(100-Length)/Length

Ohm's Law

Go Voltage = Electric Current*Resistance
