The voltage of the storage battery on subway cars is nearest to how many volts?

The voltage of storage batteries used in subway cars is typically around 36 volts. This specification is common because it provides a balance between efficiency and the ability to power the various electrical systems aboard modern trains. The choice of 36 volts aligns closely with option B, which indicates a value of 35 volts. It is important for operators to be aware of this characteristic since it impacts performance and compatibility with power systems. Understanding this voltage allows for better preparation for maintenance and operation, ensuring that all electrical components function properly.
