If the selector is in the 25 DCmA position, what is the correct current value?

When the selector is positioned at 25 DCmA, it indicates that the current value being measured or indicated is exactly 25 mA. In this context, DCmA refers to direct current milliampere, which is a unit of measurement for electric current.

The direct interpretation of the selector's position clearly signifies that the current flowing in the circuit or being measured is 25 mA. This understanding is pivotal in various applications, particularly in substations and other electrical environments where precise current levels must be monitored and maintained for system performance and safety.

The choices provided include various milliampere readings, but the setting of 25 DCmA is unequivocal in its indication of current value. Knowing how selectors work in instruments helps in accurately interpreting readings, which is crucial for effective troubleshooting and system diagnostics.
