EMF across Galvanometer Solution

STEP 0: Pre-Calculation Summary
Formula Used
EMF = Resistance*(((Current 1)^2)-((Current 2)^2))
EMF = Rh*(((I1)^2)-((I2)^2))
This formula uses 4 Variables
Variables Used
EMF - (Measured in Volt) - EMF is equal to the terminal potential difference when no current flows.
Resistance - (Measured in Ohm) - Resistance is the resistance of each heating element in a thermocouple.
Current 1 - (Measured in Ampere) - Current 1 is the current flowing through the first arm.
Current 2 - (Measured in Ampere) - Current 2 is the current flowing through the second wattmeter setup.
STEP 1: Convert Input(s) to Base Unit
Resistance: 15 Ohm --> 15 Ohm No Conversion Required
Current 1: 5 Ampere --> 5 Ampere No Conversion Required
Current 2: 3 Ampere --> 3 Ampere No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
EMF = Rh*(((I1)^2)-((I2)^2)) --> 15*(((5)^2)-((3)^2))
Evaluating ... ...
EMF = 240
STEP 3: Convert Result to Output's Unit
240 Volt --> No Conversion Required
FINAL ANSWER
240 Volt <-- EMF
