FAQ

What is EMF across Galvanometer?
The EMF across Galvanometer formula is dependent on the resistance of the heating elements and also the spring constant and is represented as EMF =Rh*(((I1)^2)-((I2)^2)) or EMF=Resistance*(((Current 1)^2)-((Current 2)^2)). Resistance is the resistance of each heating element in a thermocouple, Current 1 is the current flowing through the first arm and Current 2 is the current flowing through the second wattmeter setup.
How to calculate EMF across Galvanometer?
The EMF across Galvanometer formula is dependent on the resistance of the heating elements and also the spring constant is calculated using EMF=Resistance*(((Current 1)^2)-((Current 2)^2)). To calculate EMF across Galvanometer, you need Resistance (Rh), Current 1 (I1) and Current 2 (I2). With our tool, you need to enter the respective value for Resistance, Current 1 and Current 2 and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
