Electromotive force (emf) is the energy provided by a source per unit electric charge to move electrons through a circuit, essentially functioning as the driving force behind the flow of electric current. It is measured in volts and is not actually a force but a potential difference that can cause current to flow in a closed loop.

A closed loop system is a control system that utilizes feedback to compare the actual output with the desired output and make necessary adjustments to minimize the error. This approach enhances stability, accuracy, and performance in various applications, from industrial processes to electronic circuits.
