To determine the correct unit for electromotive force (EMF), let's examine each option:
A) Coulombs: This is the unit of electric charge, not EMF.
B) Volts: Volts is the unit of electric potential difference or electromotive force. It is defined as the difference in electric potential between two points, and it measures the work done to move a charge from one point to another.
C) Ohms: This is the unit of electrical resistance, not EMF.
D) Amps: This is the unit of electric current, not EMF.
Given this information, the correct unit of electromotive force (EMF) is:
B) Volts
So, the measured quantity electromotive force, or EMF, is recorded in volts.
