Yes, Electromotive Force (EMF) is considered a scalar quantity, not a vector.
Even though it has a direction associated with it (since it drives current in a specific direction), it is measured as a scalar because it represents the total potential difference or energy per unit charge. In equations, EMF is represented as a single value, without considering directionality like other vector quantities (e.g., electric field or magnetic field).
So, while EMF is related to forces and fields that have directions, the value itself doesn't have a directional component in the same way a vector would.
