Step 1
: Understand the question

The question asks which term describes electromotive force (EMF). EMF is the total amount of energy transferred or converted per unit charge that passes through a given point in an electrical circuit.

Step 2
: Recall the relevant concept

In the context of electrical circuits, voltage, resistance, and current are the fundamental concepts related to EMF. Voltage, measured in volts (V), is the electric potential difference between two points in a circuit. It is the driving force that moves charges around the circuit.

Final Answer

The term that describes electromotive force is B. Voltage.
