A student says “Potential difference and Emf are same.” Justify yo – InterviewSolution

1.	A student says “Potential difference and Emf are same.” Justify your answer.
Answer» Both are different because potential difference is the work done by the electric force on unit positive charge to move it through a distance between two points whereas emf is the chemical force to move unit positive charge from negative terminal to positive terminal of the battery.
