The correct answer highlights a characteristic of starting methods for electric motors, particularly the intention to reduce current flow during startup. When electric motors start, they often draw significantly higher current compared to their running state, which can cause stress on electrical systems and lead to problems like voltage drops or damage to components.

Starting methods such as star-delta starters, autotransformer starters, or soft starters are employed to limit the initial inrush current. By effectively reducing current flow during the starting phase, these methods help to minimize the electrical shock to the system and reduce mechanical stress on the motor and connected equipment.

This characteristic is particularly important in industrial settings where multiple motors may be started simultaneously or where system stability is critical. A controlled start prevents performance issues and prolongs the life of the motor and associated electrical infrastructure.
