When the control circuit power is on, which motor is energized?

• A. M1
• B. M2
• C. Both M1 and M2
• D. Neither M1 nor M2

Answer: (B)

The correct answer is that M2 is energized when the control circuit power is on. In many control circuits, specific conditions dictate which motor (M1 or M2) will receive power based on the design of the control system. Typically, the control circuit may include elements such as relays, timers, or switches that are configured to activate only certain outputs under particular conditions. If the design specifies that M2 is energized when the control circuit is powered, it suggests that this motor is connected in such a way that it receives the required current only when the control circuit is active. Understanding the specific configuration of the control circuit is crucial, as it typically indicates which components are activated based on power availability and how they are wired. This knowledge helps technicians effectively troubleshoot and maintain electrical systems, ensuring that each component functions correctly according to its intended design.
